It turns out things are not as simple as I hoped. sys/personality.h
exists on all androids but it does not define the required symbols on
all platform levels.
Add a compile check for platform level to compile against both new and
old android headers.

On android API level 9 the header does not get included transitively.
Include it directly.
As far as I can see, all non-windows platforms should have this header.
If that turns out to be incorrect, we can add some ifdefs around that.

read packet: $qXfer:features:read+;PacketSize=20000;qEcho+;SupportedCompressions=zlib-deflate;DefaultCompressionMinSize=384#00
maybe these tests should be a little more accepting of additional
features. but I didn't mean for this to be enabled on mac native.

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).

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.

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.

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
more convoluted log statements.

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.

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.

The unit test I added in the previous commit discovered a bug in
PrependPathComponent on windows -- it was calling SetFile with the host native
path syntax, whereas it should be explicitly specifying the path syntax (as
AppendPathComponent does). This fixes it.
llvm-svn: 292106
Summary:
PrependPathComponent was unconditionally inserting path separators between the
path components. This is not correct if the prepended path is "/", which caused
problems down the line. Fix the function to use the same algorithm as
AppendPathComponent and add a test. This fixes one part of llvm.org/pr31611.

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.

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.
