getcontext is also not available on musl libc, so generalize
breakpad_getcontext so it can be used as a fallback for non-Android
platforms as well.

On x86_64 and i386, ucontext_t uses an Android-specific offset for
storage of FP registers, since its sigset_t differs in size. So,
make the definition of MCONTEXT_FPREGS_MEM and UCONTEXT_FPREGS_MEM_OFFSET
conditional on whether we are building for Android.

On glibc and musl, signal.h and asm/sigcontext.h can't be included
together, so in breakpad_context_unittest.cc, only compare the libc
and kernel _fpstate when on Android.

- When type other than breakpad is specified, sym_upload tool requires

- This ultimately means that sym_upload can be used to upload native

Previously, the processor truncated the upper of two
overlapping module ranges to compensate for incorrect
reporting of module ranges by the Breakpad client.
Crashpad correctly reports module load ranges, so
this truncation strategy is no longer necessary.

However, when partitioned libraries are used, the base
library may have a range which encompasses the other
partitions. When this is combined with the truncate
upper merge strategy, the base library's executable
segment is truncated causing symbolization failures.

This patch changes Android's merge strategy to truncate
the lower range (which is still the base library, but
this strategy truncates from the high end of the
library's range, instead of its base).

I have a project where we are trying to include breakpad as a git
submodule. The only problem getting it to build with ndk-build is that
the linux_syscall_support.h header is missing. Normally, this header
would be downloaded by the depot_tools. But we cannot install
depot_tools on our CI machines.

So, we would like to include the header as a separate submodule in our
repo. The only change we would need to make to breakpad to make that
work is to add this optional variable to the C header search path. In
the normal case, this variable will not be set and nothing will be
different. But we can set the variable to allow us to build without
installing depot_tools.

I have manually tested this using a separate project that links to
breakpad in this way.
