This change was partially scripted and partially done manually with vim
regex + manually placing the deleted constructors.
The script change looked for destructors in the public: section of a
class, if that existed the deleted constructors would go before the
destructor.
For manual placement I looked for any constructor in the public: section
of the corresponding class. If there wasn't one, then it would ideally
have gone as the first entry except below enums, classes and typedefs.
This may not have been perfect, but is hopefully good enough. Fingers
crossed.

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 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.

Use the new standard pattern, and remove all vestiges of the custom

This was done previously in 79f4a3970a64, but was reverted in
bba9d0819c12 because Chromium’s test launcher did not support
GTEST_SKIP() at the time. The deficiency is on file as

When a crashing process is in a different PID namespace than the
handler, the crasher doesn't have a way of knowing its own thread ID in
the handler's namespace and the kernel lacks mechanisms to perform this
translation before Linux 4.1 (where the information is present in
/proc/<pid>/status:NSPid).
This patch gives the handler a way of identifying the requesting thread
by sending a stack address along with the crash dump request, which
the handler can search for in each of the process' threads.
This information is useful both for attaching exception information
to the right thread and to allow the handler to send signals to the
correct thread when using a shared socket connection.
