The load bias is documented to be the difference between
the preferred and actual load address for a module, but
is declared as an unsigned number, and math using it relies
on it being a pointer-precisioned two's complement number
that might cause over- or under-flow.
ElfImageReader and DebugRendezvous both provide ways to get
the load bias for a module and are corroborated in tests.
However, the load bias computed by DebugRendezvous does
not have access to the preferred address, so there is not
enough information to determine the signedness to use with
a VMOffset.
This patch compares the load biases modulo the numeric range
for a pointer to ignore the signedness of the value.
Also update the test module to trigger a negative load bias.

The broker attempts to use sbrk() to allocate memory to track ptrace
attachments. If the process failed due to an OOM, this system call might
fail, the broker falls back to saving attachments on the stack, and then
overruns the stack.
This change updates the broker to use sys_mmap() instead of sbrk(),
which is expected to work at least as well. If sys_mmap() fails or
the first mapped page is exhausted, further attachments fail without
attempting to save them to the stack.

The ELF standard allows substantial flexibility in the construction of
valid ELF modules, but there are widely followed conventions. For
example, ELF modules typically contain several segments, they do load
their program headers, and they don't load their section headers.
Bionic contains a variety of checks that the modules it's loading look
typical. Beginning with Android M, Bionic refuses to load segments which
contain the entire file contents.

LogOutputStreamTest.{WriteAbort,FlushAbort} are flaky because the logcat
is sometimes overloaded earlier than expected causing FlushAbort to fail
during Write() or either test to fail to write the abort message.
This change updates LogOutputStream to detect logcat overloads (EAGAIN)
and make one attempt at writing the abort message, even if the output
cap hasn't been reached.
This change also updates LogOutputStream's interface to defer log writes
to a Delegate. In tests, the Delegate implements a mock log and in
production, writes to Android's logcat.
I've removed VerifyGuards because LogOutputStream no longer writes
guards if Write() has never been called and the guards are tested in
other tests.
