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).

Pavel Labath e0a5b575a6 Prevent client from querying each thread's PC at each stop.
Summary:
The server was no longer sending the thread PCs the way the client
expected them.
I changed the server to send them back as a threadstop info field,
similar to the Apple version of the server.
I also changed the client to look for them there, before querying the
server.
I added a test to ensure the server doesn't stop sending them.

Hafiz Abid Qadeer 4687db0e09 Provide a substitute to load command of gdb.
For bare-metal targets, lldb was missing a command like 'load' in gdb
which can be used to create executable image on the target. This was
discussed in
http://lists.llvm.org/pipermail/lldb-dev/2016-December/011752.html

This commits adds an option to "target module load" command to provide
that functionality. It does not set the PC to entry address which will
be done separately.

Pavel Labath a6321a8e95 Refactor logging in NativeProcessLinux
Use the LLDB_LOG macro instead of the more verbose if(log) ... syntax.

I have also consolidated the log channels (everything now goes to the posix
channel, instead of a mixture of posix and lldb), and cleaned up some of the

Pavel Labath 107d9bbd6c Add a more succinct logging syntax
This adds the LLDB_LOG macro, which enables one to write more succinct log
statements.
if (log)
  log->Printf("log something: %d", var);
becomes
LLDB_LOG(log, "log something: {0}, var);

The macro still internally does the "if(log)" dance, so the arguments are only
evaluated if logging is enabled, meaning it has the same overhead as the
previous syntax.

Additionally, the log statements will be automatically prefixed with the file
and function generating the log (if the corresponding new argument to the "log
enable" command is enabled), so one does not need to manually specify this in
the log statement.

It also uses the new llvm formatv syntax, which means we don't have to worry
about PRIx64 macros and similar, and we can log complex object (llvm::StringRef,
lldb_private::Error, ...) more easily.

Pavel Labath e5cfc67113 [cmake] Make lldb build with the android ndk toolchain file
Summary:
The NDK cmake toolchain file defines CMAKE_SYSTEM_NAME=Android, so switch the
build to use that. I have also updated the in-tree toolchain file to do that
(instead of defining __ANDROID_NDK__), so it can still be used to build.
After migrating the last bits of non-toolchainy bits out of the in-tree
toolchain, I intend to delete it.

Pavel Labath 0cfd7dc9ea Remove a couple of Stream flags
Summary:
I came across this while trying to understand what Log::Debug does. It turns out
it does not do anything, as there is no instance of someone setting a debug flag
on a stream. The same is true for the Verbose and AddPrefix flags. Removing
these will enable some cleanups in the Logging class, and it brings us closer
towards the long term goal of standardizing on llvm stream classes.

I have removed these flags and all code the code which tested for their
presence -- there wasn't much of it, mostly in SymbolFileDWARF, which is
probably going away at some point anyway.

The eBinary flag still has some users, so I am letting it life for the time
being.

Pavel Labath e92b965bbf [cmake] Fix LLVM_LINK_LLVM_DYLIB build, again
The llvm_config hack for lldb-server is only necessary for !DYLIB builds, as
otherwise we would get unresolved symbols from lldb libraries which do not track
their dependencies correctly (all of them). In a DYLIB build, the so will
already be added to the link dependencies and we can use that to resolve all
missing symbols.

The proper fix for this would be to have each lldb library track its
dependencies correctly.

Pavel Labath 927ec4b5ac Consolidate file handle usage in Editline.cpp
Summary:
To implement wide character reading, editline was mixing FILE*-based access with
a Connection-based one (plus it did some selects on the raw FD), which is very
fragile. Here, I replace it with one which uses only a Connection-based reads.
The code is somewhat longer as I had to read characters one by one to detect the
end of the multibyte sequence.

I've verified that international characters still work in lldb command line on
OSX.
