Zachary Turner 97206d5727 Rename Error -> Status.
This renames the LLDB error class to Status, as discussed
on the lldb-dev mailing list.

A change of this magnitude cannot easily be done without
find and replace, but that has potential to catch unwanted
occurrences of common strings such as "Error".  Every effort
was made to find all the obvious things such as the word "Error"
appearing in a string, etc, but it's possible there are still
some lingering occurences left around.  Hopefully nothing too
serious.

Zachary Turner 2f3df6137a iwyu fixes for lldbCore.
This adjusts header file includes for headers and source files
in Core.  In doing so, one dependency cycle is eliminated
because all the includes from Core to that project were dead
includes anyway.  In places where some files in other projects
were only compiling due to a transitive include from another
header, fixups have been made so that those files also include
the header they need.  Tested on Windows and Linux, and plan
to address failures on OSX and FreeBSD after watching the
bots.

Pavel Labath 1d5855b107 Replace getcwd with the llvm equivalent
Summary:
getcwd() is not available (well.. um.. deprecated?) on windows, and the way
PosixApi.h is providing it causes strange compile errors when it's included in
the wrong order. The best way to avoid that is to just not use chdir.

This replaces all uses of getcwd in generic code. There are still a couple of
more uses, but these are in platform-specific code.

chdir() is causing a similar problem, but for that there is no llvm equivalent
for that (yet).

Hafiz Abid Qadeer f6ee79c926 Fix build for mingw.
Summary: I was building lldb using cross mingw-w64 toolchain on Linux and observed some issues. This is first patch in the series to fix that build. It mostly corrects the case of include files and adjusts some #ifdefs from _MSC_VER to _WIN32 and vice versa. I built lldb on windows with VS after applying this patch to make sure it does not break the build there.

Zachary Turner ecbb0bb169 Fix more functions in Args to use StringRef.
This patch also marks the const char* versions as =delete to prevent
their use.  This has the potential to cause build breakages on some
platforms which I can't compile.  I have tested on Windows, Linux,
and OSX.  Best practices for fixing broken callsites are outlined in
Args.h in a comment above the deleted function declarations.

Eventually we can remove these =delete declarations, but for now they
are important to make sure that all implicit conversions from
const char * are manually audited to make sure that they do not invoke a
conversion from nullptr.

Kate Stone b9c1b51e45 *** This commit represents a complete reformatting of the LLDB source code
*** to conform to clang-format’s LLVM style.  This kind of mass change has
*** two obvious implications:

Firstly, merging this particular commit into a downstream fork may be a huge
effort.  Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit.  The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):

    find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
    find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;

The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.

Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit.  There are alternatives available that will attempt
to look through this change and find the appropriate prior commit.  YMMV.

Pavel Labath 998bdc5b75 Generalize child process monitoring functions
Summary:
This replaces the C-style "void *" baton of the child process monitoring functions with a more
C++-like API taking a std::function. The motivation for this was that it was very difficult to
handle the ownership of the object passed into the callback function -- each caller ended up
implementing his own way of doing it, some doing it better than others. With the new API, one can
just pass a smart pointer into the callback and all of the lifetime management will be handled
automatically.

This has enabled me to simplify the rather complicated handshake in Host::RunShellCommand. I have
left handling of MonitorDebugServerProcess (my original motivation for this change) to a separate
commit to reduce the scope of this change.

Enrico Granata 7a37df3fc3 Improve the way LLDB escapes arguments before passing them to the shell
Teach LLDB that different shells have different characters they are sensitive to, and use that knowledge to do shell-aware escaping

This helps solve a class of problems on OS X where LLDB would try to launch via sh, and run into problems if the command line being passed to the inferior contained such special markers (hint: the shell would error out and we'd fail to launch)
This makes those launch scenarios work transparently via shell expansion

Slightly improve the error message when this kind of failure occurs to at least suggest that the user try going through 'process launch' directly

Processes now need to take a ListenerSP, not a Listener&.

This required changing over the Process plugin class constructors to take a ListenerSP, instead

Zachary Turner 270e99ab0a Fix some posix assumptions related to running shell commands.
This is a resubmit of r223548, which was reverted due to breaking
tests on Linux and Mac.

This resubmit fixes the reason for the revert by adding back some
accidentally removed code which appends -c to the command line
when running /bin/sh.

This resubmit also differs from the original patch in that it sets
the architecture on the ProcessLaunchInfo.  A follow-up patch will
refactor this to separate the logic for different platforms.

Greg Clayton 8012cadbf3 Fixed more fallout from running the test suite remotely on iOS devices.
Fixed include:
- Change Platform::ResolveExecutable(...) to take a ModuleSpec instead of a FileSpec + ArchSpec to help resolve executables correctly when we have just a path + UUID (no arch).
- Add the ability to set the listener in SBLaunchInfo and SBAttachInfo in case you don't want to use the debugger as the default listener. 
- Modified all places that use the SBLaunchInfo/SBAttachInfo and the internal ProcessLaunchInfo/ProcessAttachInfo to not take a listener as a parameter since it is in the launch/attach info now
- Load a module's sections by default when removing a module from a target. Since we create JIT modules for expressions and helper functions, we could end up with stale data in the section load list if a module was removed from the target as the section load list would still have entries for the unloaded module. Target now has the following functions to help unload all sections a single or multiple modules:

    size_t
    Target::UnloadModuleSections (const ModuleList &module_list);

    size_t
    Target::UnloadModuleSections (const lldb::ModuleSP &module_sp);

Todd Fiala 75f47c3a5d llgs: fixes to PTY/gdb-remote inferior stdout/stderr handling, logging addtions.
With this change, both local-process llgs and remote-target llgs stdout/stderr
handling from inferior work correctly.

Several log lines have been added around PTY and stdout/stderr redirection
logic on the lldb client side.

Regarding remote llgs execution, see the following:

With these changes, remote llgs with $O now works properly:

$ lldb
(lldb) platform select remote-linux
(lldb) target create ~/some/inferior/exe
(lldb) gdb-remote {some-target}:{port}
(lldb) run

The sequence above will correctly redirect stdout/stderr over gdb-remote $O,
as is needed for remote debugging.  That sequence assumes there is a lldb-gdbserver
exe running on the target with {some-host}:{port}.

You can replace the gdb-remote command with a '(lldb) platform connect
connect://{target-ip}:{target-port}'.  If you do this and have a
lldb-platform running on the remote end, it will go ahead and launch
llgs for lldb for each target instance that is run/attached.

For local debugging with llgs, the following sequence also works, and
uses local PTYs instead to avoid $O and extra gdb-remote messages:

$ lldb
(lldb) settings set platform.plugin.linux.use-llgs true
(lldb) target create ~/some/inferior/exe
(lldb) run

The above will run the inferior using llgs on the local host, and
will use PTYs rather than $O redirection.

This change also removes the logging that happened after the fork but
before the exec when llgs is launching a new inferior process.  Some
aspect of the file handling during that portion of code would not do
the right thing with log handling.  We might want to go back later
and have that communicate over a pipe from the child to parent to pass
along any messages that previously were logged in that section of code.
