5b35d1980c Fix android build
getpwent is not available on android until API level 21, and even then
it is only available when doing a non-static link. Since android's
concept of users is very different from linux, it's doubtful the home
directory resolution would be useful, so I approximate this state by
just not using getpwent on android.

We've had another getpwent occurance in FileSpec for a while -- it
wasn't causing problems because it was stripped out by the linker, but I
disable that also, for consistency's sake.

1f8753479e Use LLVM for file / directory enumeration.
FileSpec::EnumerateDirectory has a bunch of platform-specific
gunk in it for posix and non-posix platforms. We can get rid
of all this by using LLVM's easy-to-use directory iterators.

30e6cbfcfc Revert "Use LLVM for all stat-related functionality."
this reverts r297116 because it breaks the unittests and
TestCompDirSymlink. The ModuleCache unit test is trivially fixable, but
the CompDirSymlink failure is a symptom of a deeper problem: llvm's stat
functionality is not a drop-in replacement for lldb's. The former is
based on stat(2) (which does symlink resolution), while the latter is
based on lstat(2) (which does not).

This also reverts subsequent build fixes (r297128, r297120, 297117) and
r297119 (Remove FileSpec dependency on FileSystem) which builds on top
of this.

7f6a7a3752 Remove FileSpec::ReadFileContents.
This functionality is subsumed by DataBufferLLVM, which is
also more efficient since it will try to mmap.  However, we
don't yet support mmaping writable private sections, and in
some cases we were using ReadFileContents and then modifying
the buffer.  To address that I've added a flag to the
DataBufferLLVM methods that allow you to map privately, which
disables the mmaping path entirely.  Eventually we should teach
DataBufferLLVM to use mmap with writable private, but that is
orthogonal to this effort.

3f4a4b3681 Delete DataBufferMemoryMap.
After a series of patches on the LLVM side to get the mmaping
code up to compatibility with LLDB's needs, it is now ready
to go, which means LLDB's custom mmapping code is redundant.
So this patch deletes it all and uses LLVM's code instead.

In the future, we could take this one step further and delete
even the lldb DataBuffer base class and rely entirely on
LLVM's facilities, but this is a job for another day.

33aba3c290 Get rid of Error::PutToLog().
Instead just rely on LLDB_LOG().

This is part of an effort to sort out dependency hell in LLDB.
Error is in Utility, but Log is in Core.  Core can depend on
Utility, but not vice versa.  So this patch moves the knowledge
about how to log Errors from the Error class to the Log file.

Summary:
The std::call_once implementation in libstdc++ has problems on few systems: NetBSD, OpenBSD and Linux PPC. LLVM ships with a homegrown implementation llvm::call_once to help on these platforms.

This change is required in the NetBSD LLDB port. std::call_once with libstdc++ results with crashing the debugger.

bf9a77305f Move classes from Core -> Utility.
This moves the following classes from Core -> Utility.

ConstString
Error
RegularExpression
Stream
StreamString

The goal here is to get lldbUtility into a state where it has
no dependendencies except on itself and LLVM, so it can be the
starting point at which to start untangling LLDB's dependencies.
These are all low level and very widely used classes, and
previously lldbUtility had dependencies up to lldbCore in order
to use these classes.  So moving then down to lldbUtility makes
sense from both the short term and long term perspective in
solving this problem.

 - In LaunchProcess declaration change virtual to override.

494f277af5 [CMake] Add accurate dependency specifications
Summary:
This patch adds accurate dependency specifications to the mail LLDB libraries and tools.

In all cases except lldb-server, these dependencies are added in addition to existing dependencies (making this low risk), and I performed some code cleanup along the way.

For lldb-server I've cleaned up the LLVM dependencies down to just the minimum actually required. This is more than lldb-server actually directly references, and I've left a todo in the code to clean that up.
