this was needed because lldb-mi temporarily contained references to private lldb symbols
(lldb_private namespace), which it shouldn't have. The situation has since been rectified and
this wasn't the right fix anyway, since it can lead to funny ODR violations.

FileSystem::Fopen is a lldb_private API, but lldb-mi uses only the
public API. Depending on lldb_private APIs makes Xcode builds fail.
I reverted the portion of r264074 that added such a dependency.

Win32 API calls that are Unicode aware require wide character
strings, but LLDB uses UTF8 everywhere. This patch does conversions
wherever necessary when passing strings into and out of Win32 API

We want to do a better job presenting errors that occur when evaluating
expressions. Key to this effort is getting away from a model where all
errors are spat out onto a stream where the client has to take or leave
all of them.
To this end, this patch adds a new class, DiagnosticManager, which
contains errors produced by the compiler or by LLDB as an expression
is created. The DiagnosticManager can dump itself to a log as well as
to a string. Clients will (in the future) be able to filter out the
errors they're interested in by ID or present subsets of these errors
to the user.
This patch is not intended to change the *users* of errors - only to
thread DiagnosticManagers to all the places where streams are used. I
also attempt to standardize our use of errors a bit, removing trailing
newlines and making clients omit 'error:', 'warning:' etc. and instead
pass the Severity flag.
The patch is testsuite-neutral, with modifications to one part of the
MI tests because it relied on "error: error:" being erroneously
printed. This patch fixes the MI variable handling and the testcase.

The Windows SDK provides a version of signal() that is much more
limited compared to other platforms. It only supports about 5-6
signal values. LLDB uses signals for a number of things, most
notably to handle Ctrl+C so we can gracefully shut down. The
portability solution to this on Windows has been to provide a
hand-rolled implementation of `signal` using the name `signal`
so that you could write code that simply calls signal directly
and it would work.
But this introduces a multiply defined symbol with the builtin
version and depending on how you included header files, you could
get yourself into a situation where you had linker errors. To
make matters worse, it led to a ton of compiler warnings. Worst
of all though is that this custom implementation of signal was,
in fact, identical for the purposes of handling Ctrl+C as the
builtin implementation of signal. So it seems to have literally
not been serving any useful purpose.
This patch deletes all the custom signal() functions for Windows,
and includes the signal.h system header, so that any calls to
signal now go to the actual version provided by the Windows SDK.

This patch adds support the command 'source info' as follows:
(lldb) help source info
Display source line information (as specified) based on the current executable's
debug info.
Syntax: source info <cmd-options>
Command Options Usage:
source info [-c <count>] [-s <shlib-name>] [-f <filename>] [-l <linenum>] [-e <linenum>]
source info [-c <count>] [-s <shlib-name>] [-n <symbol>]
source info [-c <count>] [-a <address-expression>]
-a <address-expression> ( --address <address-expression> )
Lookup the address and display the source information for the corresponding
file and line.
-c <count> ( --count <count> )
The number of line entries to display.
-e <linenum> ( --end-line <linenum> )
The line number at which to stop displaying lines.
-f <filename> ( --file <filename> )
The file from which to display source.
-l <linenum> ( --line <linenum> )
The line number at which to start the displaying lines.
-n <symbol> ( --name <symbol> )
The name of a function whose source to display.
-s <shlib-name> ( --shlib <shlib-name> )
Look up the source in the given module or shared library (can be specified
more than once).
For example:
(lldb) source info --file x.h
Lines for file x.h in compilation unit x.cpp in `x
[0x0000000100000d00-0x0000000100000d10): /Users/dawn/tmp/./x.h:10
[0x0000000100000d10-0x0000000100000d1b): /Users/dawn/tmp/./x.h:10
The new options are used to fix the MI command:
-symbol-list-lines <file>
which didn't work for header files because it called:
target modules dump line-table <file>
which only dumps line tables for a compilation unit.
The patch also fixes a bug in the error reporting when no files were supplied to the command. Previously you'd get:
(lldb) target modules dump line-table
error:
Syntax:
error: no source filenames matched any command arguments
Now you get:
error: file option must be specified.

Summary:
I observed that eclipse was passing --thread-group for many other commands
then we are currently handling. Looking at the MI documentation, the
following link states that each MI command accept the --thread and
--frame option. Looking at the GDB implementation, it seems that apart
from these 2, --thread-group is also handled the same way.

So instead of handling those arguments in every comamnds, I have moved
them into the base class and removed them from elsewhere. Now any command
can use these arguments. The patch seems big but most of the changes are

A variable of type:
struct S {
union {
int i1;
unsigned u1;
};
union {
int i2;
unsigned u2;
};
};
had been impossible to evaluate in lldb-mi, because MI assigns '??' as the
variable name to each of the unnamed unions after "-var-list-children" command.
Also '??' incorrectly goes to 'exp' field which is treated by IDE as a
structure field name and is displayed in watch window.
The patch fixes this returning empty string as type name for unnamed union and
assigning $N to variable name, where N is the field number in the parent entity.

In r248047, I attempted to fix a build breakage introduced by using
llvm's regex support from lldb-mi. However, my approach was flawed
when LLVM and lldb are dynamically linked, in which case two copies
of LLVMSupport would end up in memory, causing crashes on lldb start up.
Instead, use LINK_COMPONENTS to make sure lldb-mi has access to the
LLVMSupport symbols without causing duplication in the dynamic library
case.
llvm-svn: 250751
If a string contained characters outside the ASCII range, lldb-mi would
print them as hexadecimal codes. This patch fixes this behaviour by
converting to UTF-8 instead, by having lldb-mi use registered type
summary providers, when they are available. This patch also fixes
incorrect evaluation of some composite types, like std::string, by
having them use a type registered type summary provider.

to the -s option in the lldb command line interpreter:
process launch -s

"exec-run-start-option" is in the list of options reported by the lldb-mi

CMICmdArgSet stores a vector of non-const pointers to the arguments
that it is validating. It owns them and is responsible for deleting
them.
We don't need to pass a const reference to the argument to
CMICmdArgSet::Add and then take the address and const_cast it
when we can just pass the argument pointer in directly.
This lets us remove some noise at every call site for CMICmdArgSet::Add
and then clean up a couple of bits inside CMICmdArgSet to remove
const_casts.

1. To handle the expression with spaces, this command uses 2 arguments. For a case
like -break-condition 1 i == 5, the first will pick the 'i' and second will
pick the '== 5'. But the second argument was made mandatory which failed in
cases when there was no space in the expression like i==5.
2. The function GetRestOfExpressionNotSurroundedInQuotes has 2 locals with the
same names. It resulted in one hiding the other and this function always
returned empty string.
No regression on Linux. Committed as obvious.

Summary:
This also moves the xcode support files to be near or the same
as the ones used for cmake.
The source/API/liblldb.xcodes.exports differs from the
source/API/liblldb.exports in that one contains the actual
symbol names (_ prefixed) while the other contains the symbol
names as they are in the code. The liblldb.exports file is
preprocessed by the cmake scripts into the correct per-platform
file needed (like a linker script on Linux).
This is not enabled on Windows as Windows doesn't use the same
name mangling and so it won't be valid there. Also, this is handled
already in a different way on Windows (via dll exports).
