Use __inline__ for fortify.

libunwind has #define inline /* empty */ which breaks our fortified headers.
glibc uses __inline but our BSD-derived headers often override that. __inline__
is the third alternative understood by GCC that -- as far as I know -- neither
the C library itself nor third-party code tries to mess with.

Kill <machine/_types.h>.

Most of <machine/_types.h> was either unused, wrong, or identical across
all 32-/64-bit architectures.

I'm not a huge fan of <sys/_types.h> either, but moving the bits we need
up into there is a step forward.

Fix <link.h>.

Also move some of the stuff that should be in <link.h> out of the
private "linker.h", to make it clearer that these are public API
known to gdb that we can't change.

Clean up cacheflush.

No cacheflush for LP64; use the GCC builtin instead. Clean up the
32-bit MIPS implementation now we no longer need to worry about
old versions of GCC.

Fix a leak on error in tzload.

Change-Id: Ib5d9aaa7a618e478ce8e5e82f967cf535bb1a5a3
Vastly reduce the number of read(2)s done in tzload.

This costs us about 1000 fewer syscalls, which makes "adb shell strace date"
a lot more readable (which is the reason I've been meaning to fix this for a
long time now), but also actually saves a measurable amount of time.

Longer-term we should try to keep the tzdata mmap(2)ed in like libcore
does.
