Also add --disable-bootstrap and some verbiage as to how to speed
up the GCC build even further.

- add configure option --enable-ubsan
- add __ubsan helpers (by Julian)
This requires gcc 4.9.2 or later. Not all platforms are supported, though.
With this change and VEX r3099 regression tests pass on amd64
with a valgrind compiled with -fsanitize=undefined.

than asking her to recompile.
Part of fixing BZ #337869.

which, despite the name, is a pointer to an unsigned long.
So we should be passing arguments of matching type.

HAVE_DLINFO_RTLD_DI_TLS_MODID.
* add the copyright notice in auxprogs/getoff.c
* add more prereq to hgtls.vgtest

To implement QGetTlsAddr, gdbsrv has to know how to get the glibc dtv
address and the module id from the link_map.
These 2 things are dependent on the internals of glibc.
The dependency is mostly isolated in a few lines of arch dependent
code or in an external utility that used a hack + -ldl lib to find
the offset of the modid in the link_map structure.
Tested on x86/amd64/ppc64/s390x. Somewhat tested on ppc32 and arm64.
Untested/a few #ifdef-ed lines not compiled on arm/mips32/mips64
and darwin.

Changes:
* auxprogs/getoff.c new auxilliary program to get platform specific offsets
(currently only the offset for the module id in struct link_map).
* configure.ac : check for dlinfo(RTLD_DI_TLS_MODID) needed for getoff.c
* new gdbserver_tests/hgtls, testing various types of __thread variables
* various m_gdbserver files:
- implement decoding of the QGetTlsAddr query
- for each platform: platform specific code to get the dtv
- call to external program getoff-<platform> the first time an
__thread variable is printed.

requested file is not found by the server. This makes it easier to
diagnose client--server communications problems.

* add a new flag --allow-mismatched-debuginfo to override the
CRC32/build-id checks, if needed
* tidy up logic for finding files on the --extra-debuginfo-path
and at the --debuginfo-server
* don't assert if connection to the debuginfo server is lost;
instead print a reasonable message and quit.
