fa432524a6 Mark __BIONIC_WEAK_FOR_NATIVE_BRIDGE symbols
To make it easier for Native Bridge implementations
to override these symbols.

Bug: http://b/67993967
Test: make

d4ca231ae2 Unified sysroot: kill arch-specific include dirs.
<machine/asm.h> was internal use only.

<machine/fenv.h> is quite large, but can live in <bits/...>.

<machine/regdef.h> is trivially replaced by saying $x instead of x in
our assembler.

<machine/setjmp.h> is trivially inlined into <setjmp.h>.

<sgidefs.h> is unused.

Bug: N/A

3299590dfe Add a checksum to jmp_buf on mips and mips64.
Make it easier to diagnose applications mucking with the contents of
jmp_buf by checksumming its contents.

dd57029ed1 Simplify three copyright headers.
There's no reason to have multiple years in our own copyright headers,
and given the stupidity of our NOTICE file generation, it just creates
more junk.

b6d301f42d [MIPS] Fix setjmp signals
Include full 16-byte Mips sigset_t signal mask within jump buffer.
Call sigprocmask instead of sigblockmask/sigsetmask to get/set full signal mask.
Include sigsetjmp's savesigs arg inside jmp_buf, instead of following it.
Reserve room for future extensions.
Preserve historically-large mips32 _JBLEN size.
Eliminate redundancy: code setjmp and _setjmp as tail calls into sigsetjmp,
and make longjmp and _longjmp aliases of siglongjmp.

dd37251c47 [MIPSR6] setjmp supports mips32r6 and FP64A/FPXX reg models
Save and restore floating point registers via 64-bit
load/stores when possible.  Use assembler's builtin macro
ops to generate pairs of 32-bit load/stores on Mips I cpus.

Some cpus or FR modes have only 16 even-numbered dp fp regs.
This is exposed by _MIPS_FPSET, defined by existing compilers.

851e68a240 Unify our assembler macros.
Our <machine/asm.h> files were modified from upstream, to the extent
that no architecture was actually using the upstream ENTRY or END macros,
assuming that architecture even had such a macro upstream. This patch moves
everyone to the same macros, with just a few tweaks remaining in the
<machine/asm.h> files, which no one should now use directly.

I've removed most of the unused cruft from the <machine/asm.h> files, though
there's still rather a lot in the mips/mips64 ones.

c1b44ecc53 Revert "libc: Provide ucontext_t/mcontext_t/<sys/ucontext.h>"
This creates build issues in the internal Android tree.
Will investigate later.

c124baaf29 libc: Provide ucontext_t/mcontext_t/<sys/ucontext.h>
This patch updates the C library headers to provide ucontext_t
definitions for three architectures.

+ Fix <signal.h> to always define 'struct sigcontext'.

The new declarations are announced with new macros defined in
<sys/cdefs.h> in order to make it easier to adapt client code
that already defines its own, incompatible, versions of the
structures seen here.
