This relands I12a0f907753fefd1997ab8b4ea2ac331234093cf along with
a fix to blueprint for absolute paths.
Store the current working directory and then change to the root
directory so that all file accesses must go through helpers in
the android package that properly track dependencies.

This change modifies the location of generated compdb file from
$ANDROID_BUILD_TOP to where compdbOtuputProjectsDirectory points to,
under $OUT_DIR. This is especially required for the build environment
that maps $ANDROID_BUILD_TOP as read-only, such as Gitc.

Native compiler flags are currently applied in approximately:
global cflags
local cflags
local include dirs
global include dirs
global conlyflags
local conlyflags
global cppflags
local cppflags
This means that a flag that is enabled in the global cppflags
cannot be disabled in the local cflags, and an Android.bp author
must know to disable it in the local cppflags. A better order
would be:
global cflags
global conlyflags
global cppflags
local cflags
local conlyflags
local cppflags
local include dirs
global include dirs
We are mixing both the global and local cflags into a single
variable, and similar for conlyflags and cppflags, which
prevents reordering them. This CL prepares to reorder them
by splitting the global and local cflags into separate variables.

Some language servers (vscode) seem to have started to rely on the
compiler being an absolute path recently. This updates the compdb
generator to match this expectation.

Some tools (eg ccls) require that the compiler in argv[0] of the
compdb be an actual compiler binary. Until now we had simply filled
that slot with /bin/false. This change fills it with the current
default clang binary instead.

compdb.go was incorrectly splitting compiler arguments. This could
cause empty strings to be included in compile_commands.json,
potentially confusing tools.

Some tools (i.e. you-complete-me) make use of a 'compdb' file
(compile_commands.json) that records (among other things) the
arguments needed to compile a file. These tools can use this with
libclang to provide semantic completions and perform other IDE
actions. This CL adds support for soong to generate a (simple)
compile_commands.json file.
