The sys_mmap/sys_mmap2 weirdness has been cleaned up in lss now and there
is only one API now for everyone -- sys_mmap.

This preserves full build ids in minidumps, which are useful for
tracking down the right version of system libraries from Linux
distributions.
The default build id produced by GNU binutils' ld is a 160-bit SHA-1
hash of some parts of the binary, which is exactly 20 bytes:
https://sourceware.org/binutils/docs-2.26/ld/Options.html#index-g_t_002d_002dbuild_002did-292
The bulk of the changes here are to change the signatures of the
FileID methods to use a wasteful_vector instead of raw pointers, since
build ids can be of arbitrary length.
The previous change that added support for this in the processor code
preserved the return value of `Minidump::debug_identifier()` as the
current `GUID+age` treatment for backwards-compatibility, and exposed
the full build id from `Minidump::code_identifier()`, which was
previously stubbed out for Linux dumps. This change keeps the debug ID
in the `dump_syms` output the same to match.

With this change Breakpad can be compiled for MIPS64,
but it is not yet functional.

PageAllocator maps memory via sys_mmap(), implemented in
linux_syscall_support.h. We need to explicitly inform MSan that this memory is
initialized.

This is an initial attempt to add Arm64 (aarch64) support to Breakpad for
Linux / Android platforms. This CL adds the Arm64 data structures, but does
not yet implement the Android getcontext support or CPUFillFromThreadInfo /
CPUFillFromUContext.

proposal for the fix.
There's a bug in the new allocator<T> implementation used by wasteful_vector. It inherits the base class' implementation of allocator and doesn't implement allocate() so it goes to the heap instead of the PageAllocator -- the very thing wasteful_vector was trying to avoid! As a side effect it was also leaking heap memory.
Thanks,
-Ivan

This is a followup change from https://breakpad.appspot.com/569002/
This prevents push_back from ever calling Realloc()
with 0 (which could happen if wasteful_vector was
constructed with size_hint set to 0, causing
allocated_ to be 0.

This patch is part of a bigger patch that helps merging the breakpad code
with the modified version in Chromium OS.
Specifically, this patch makes the following changes:
1. Add two convenient methods, back() and empty(), to the wasteful_vector
class.
2. Refactor the LinuxDumper class such that it can later be splitted into
a base class and two derived classes, one uses the current ptrace
implementation and one uses a core file.
3. Refactor the MinidumpWriter class such that it can later use different
derived implementations of LinuxDumper.
BUG=455
TEST=Tested the following:
1. Build on 32-bit and 64-bit Linux with gcc 4.4.3 and gcc 4.6.
2. Build on Mac OS X 10.6.8 with gcc 4.2 and clang 3.0 (with latest gmock).
3. All unit tests pass.
