Fixes include:
- use FileSystem::Unlink() instead of a direct call to ::unlink(...) when deleting files when iterating through the current directory
- save directories from current directory in a list and iterate through those _after_ the current directory has been iterated
- Use new FileSpec::ForEachItemInDirectory() instead of manually iterating across directories with opendir()/readdir()/closedir()
We should switch all code over to using FileSpec::ForEachItemInDirectory(...) in the near future and get rid of FileSpec::EnumerateDirectory().
This is a follow up patch to:

Summary:
`IsRelativeToCurrentWorkingDirectory` was misleading, because relative paths
are sometimes appended to other directories, not just the cwd. Plus, the new
name is shorter. Also added `IsAbsolute` for completeness.

This should solve the issue of sending denormalized paths over gdb-remote
if we stick to GetPath(false) in GDBRemoteCommunicationClient, and let the
server handle any denormalization.

Previously, users on Windows had to manually specify PYTHONPATH
to point to the site-packages directory before running LLDB.
The reason for this was because sys.path was being initialized
with a path containing unescaped backslashes, causing escape
sequences to end up in the paths.

Summary:
Before this fix the FileSpec::GetPath() returned string which might be without '\0' at the end.
It could have happened if the size of buffer for path was less than actual path.
Test case:
```
FileSpec test("/path/to/file", false);
char buf[]="!!!!!!";
test.GetPath(buf, 3);
```
Before fix:
```
233 FileSpec test("/path/to/file", false);
234 char buf[]="!!!!!!";
235 test.GetPath(buf, 3);
236
-> 237 if (core_file)
238 {
239 if (!core_file.Exists())
240 {
(lldb) print buf
(char [7]) $0 = "/pa!!!"
```
After fix:
```
233 FileSpec test("/path/to/file", false);
234 char buf[]="!!!!!!";
235 test.GetPath(buf, 3);

-> 237 if (core_file)

This is implemented by making a new FileSystem function:
bool
FileSystem::IsLocal(const FileSpec &spec)
Then using this in a new function:
DataBufferSP
FileSpec::MemoryMapFileContentsIfLocal(off_t file_offset, size_t file_size) const;
This function only mmaps data if the file is a local file since that means we can reliably page in data. We were experiencing crashes where people would use debug info files on network mounted file systems and that mount would go away and cause the next access to a page that wasn't paged in to crash LLDB.
We now avoid this by just copying the data into a heap buffer and keeping a permanent copy to avoid the crash. Updated all previous users of FileSpec::MemoryMapFileContentsIfLocal() in ObjectFile subclasses over to use the new FileSpec::MemoryMapFileContentsIfLocal() function.

For some time, eclipse (CDT) uses full path of the file in break-insert command
when putting breakpoint on a source line. On windows, a typical command looks
like the following.
56-break-insert -f F:\\work\\ws\\test\\main.c:49
Current implementation in lldb-mi have problem in 2 ways.
1. It was assuming that there will be only one : in the path which is wrong if full
path is supplied.
2. CDT sends out path with double backslashes in windows which gives error on
resolution.
Fixed the : issue in lldb-mi. Changed FileSpec::Normalize to make sure that it
handles the path with \\ correctly. Added test cases to check for full path in
both lldb-mi and lldb. Also added a test case to check SBFileSpec with double
slashes.

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.

relative paths, like:
/whatever/llvm/lib/Sema/../../include/llvm/Sema/
That causes problems with our type uniquing, since we use the declaration file
and line as one component of the uniquing, and different ways of getting to the
same file will have different directory spellings, though they are functionally
equivalent. We end up with two copies of the exact same type because of this,
and that makes the expression parser give "duplicate type" errors.
I added a method to resolve paths with ../ in them and used that in the FileSpec::Equals,
for comparing Declarations and for doing Breakpoint compares as well, since they also
suffer from this if you specify breakpoints by full path (since nobody knows what
../'s to insert...)

More specifically, this change can be summarized as follows:
1) Makes an lldbHostPosix library which contains code common to
all posix platforms.
2) Creates Host/FileSystem.h which defines a common FileSystem
interface.
3) Implements FileSystem.h in Host/windows and Host/posix.
4) Creates Host/FileCache.h, implemented in Host/common, which
defines a class useful for storing handles to open files needed
by the debugger.

This patch adds the notion of a "path syntax" to FileSpec. There
are two syntaxes (Posix and Windows) and one "meta syntax",
Host Native, which uses the current platform to figure out the
appropriate syntax for host paths.
This allows paths from one platform to be represented and
manipulated on another platform even if they have different path
syntaxes.

if err.Success():
print >> result, 'Connected to remote platform:'
print >> result, 'hostname: %s' % (remote_platform.GetHostname())
src = lldb.SBFileSpec("/Applications/Xcode.app/Contents/SharedFrameworks/LLDB.framework", False)
dst = lldb.SBFileSpec()
# copy src to platform working directory since "dst" is empty
err = remote_platform.Install(src, dst);
if err.Success():
print >> result, '%s installed successfully' % (src)
else:
print >> result, 'error: failed to install "%s": %s' % (src, err)
Implemented many calls needed in lldb-platform to be able to install a directory that contains symlinks, file and directories.
The remote lldb-platform can now launch GDB servers on the remote system so that remote debugging can be spawned through the remote platform when connected to a remote platform.
The API in SBPlatform is subject to change and will be getting many new functions.

Summary:
This merge brings in the improved 'platform' command that knows how to
interface with remote machines; that is, query OS/kernel information, push
and pull files, run shell commands, etc... and implementation for the new
communication packets that back that interface, at least on Darwin based
operating systems via the POSIXPlatform class. Linux support is coming soon.
Verified the test suite runs cleanly on Linux (x86_64), build OK on Mac OS
X Mountain Lion.
Additional improvements (not in the source SVN branch 'lldb-platform-work'):
- cmake build scripts for lldb-platform
- cleanup test suite
- documentation stub for qPlatform_RunCommand
- use log class instead of printf() directly
- reverted work-in-progress-looking changes from test/types/TestAbstract.py that work towards running the test suite remotely.
- add new logging category 'platform'
