There were crashes when android failed to extract
zip archives due to out of free space on disk, with stacks like:
#00 pc 00000000000156b0 /system/lib64/libc.so (memcpy+176)
#01 pc 000000000002e5b8 /system/lib64/libandroidfw.so
#02 pc 000000000002f488 /system/lib64/libandroidfw.so (ExtractToMemory+328)
#03 pc 000000000002f5c8 /system/lib64/libandroidfw.so (ExtractEntryToFile+268)
#04 pc 00000000000287d8 /system/lib64/libandroidfw.so (android::ZipFileRO::\
uncompressEntry(void*, int) const+12)
Space for the file is now allocated using fallocate rather than
ftruncate, since ftruncate dont actually reserve space on disk. When writes
to the mmaped pointer fails to be realized due to out of space SIGBUS
is the result. With this change we make sure that there is space available
before mmaping the pointer.

It looks like we can't use clang on Windows yet because libc++ isn't ready.
So move back to GCC for the Windows host clang. Work around the mingw
printf format string problems that made us want to switch to clang in the
first place, and #include "sysdeps.h" in adb_utils.cpp to work around the
absence of lstat(2) on Windows.

This doesn't fix the injection vulnerability, but it makes "adb backup"
no worse than the other commands, and lets me fix them all at once.

Incorrectly set $ADB_VENDOR_KEYS is the most likely cause of failed
adb connections. Make it easier to debug such problems by including
the value in use in the error message.

Fix broken mips64 build by replacing mips32r2-only android_memset.S.
Use HW-bonded pairs of 64-bit stores to fill 128 bits/cycle.
Rely on HW automatic cache prefetch optimizations.
Software cache prefetching is counterproductive on next mips cores.
New method is coded in C, and also works okay on non-Mips architectures.

libc++.so is not widely available on the host, so we compile against
one built as part of the platform. This causes problems for adb and
fastboot, which are distributed through a number of channels - the
sdk, distro packages, downloaded from the build server, or manually
copied. Instead of forcing all users to handle libc++.so too,
statically link against libc++.

cutils/endian.h provides the helpers defined in endian(3), either by
pulling in the OS's built-in endian.h (where available) or recreating
them using GCC builtins.
