Summary:
This adds support for building libc++ tests when targetting android. The
tests are still not passing due to several other problems, but this way
we can at least build them.

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.

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.

This reverts commit a6a29374662716710f80c8ece96629751697841e.
It has a few compilation failures that I don't have time to fix
at the moment.

There were a couple of problems with this function on Windows. Different
separators and differences in how tilde expressions are resolved for
starters, but in addition there was no clear indication of what the
function's inputs or outputs were supposed to be, and there were no tests
to demonstrate its use.
To more easily paper over the differences between Windows paths,
non-Windows paths, and tilde expressions, I've ported this function to use
LLVM-based directory iteration (in fact, I would like to eliminate all of
LLDB's directory iteration code entirely since LLVM's is cleaner / more
efficient (i.e. it invokes fewer stat calls)). and llvm's portable path
manipulation library.
Since file and directory completion assumes you are referring to files and
directories on your local machine, it's safe to assume the path syntax
properties of the host in doing so, so LLVM's APIs are perfect for this.
I've also added a fairly robust set of unit tests. Since you can't really
predict what users will be on your machine, or what their home directories
will be, I added an interface called TildeExpressionResolver, and in the
unit test I've mocked up a fake implementation that acts like a unix
password database. This allows us to configure some fake users and home
directories in the test, so we can exercise all of those hard-to-test
codepaths that normally otherwise depend on the host.

about this more I realized I could make the change isolated to
whether we decide an empty accelerator table is valid or not.
<rdar://problem/30867462>
llvm-svn: 297496
HasContent. If we have a valid accelerator table which has no
content, we want to depend on that (empty) table as the authoritative
source instead of reading through all the debug info for lookups.

SectionLoadList exposed by this test. Greg tried to chase it down
& got pretty far but the isn't correct so we'll disable this test
for now until I can figure that out.

This is necessary to get debug builds of unit tests working on linux.
I think we are at a point where removing dependencies does not prevent
us from depending on the whole world yet. What it does do though, is
make the dependency chains longer as the dependency graph gets sparser,
which means we need to repeat the libraries more times to get the thing
to link.

Summary:
This fixes two threading issues in the logging code. The access to the
mask and options flags had data races when we were trying to
enable/disable logging while another thread was writing to the log.
Since we can log from almost any context, and we want it to be fast, so
I avoided locking primitives and used atomic variables instead. I have
also removed the (unused) setters for the mask and flags to make sure
that the only way to set them is through the enable/disable channel
functions.
I also add tests, which when run under tsan, verify that the use cases
like "doing an LLDB_LOGV while another thread disables logging" are
data-race-free.

This was originall reverted due to some test failures in
ModuleCache and TestCompDirSymlink. These issues have all
been resolved and the code now passes all tests.

The toolchain directory for arm android targets was computed
incorrectly. The architecture part should be arm, and the environment
part androideabi. This fixes that.

If QPassSignals packaet is supported by lldb-server, lldb-client will
utilize it and ask the server to ignore signals that don't require stops
or notifications.
Such signals will be immediately re-injected into inferior to continue
normal execution.

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.

This deletes LLDB's FileType enumeration and replaces all
users, and all calls to functions that check whether a file
exists etc with corresponding calls to LLVM.

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.

it was accessing the details of the Log class directly. Let it go
through the channel class instead.
This also discovered a bug when we were setting but not clearing the log
options when enabling a channel.

Currently on remote platforms the lldb-mi tests fail, which means they time out.
Given how many of the lldb-mi tests there are, this means a long wait.
