b393e93e7b Filter out gdb file transfer warnings in gdbserver_tests/filter_stderr. 
GDB is correct that we don't support that at the moment.
See bug #351792 - vgdb doesn't support remote file transfers.

b00530b6de Distinguish properly when to establish the client data segment. 
Initial data segment is established (see initimg-solaris.c for rationale):
- directly during client program image initialization,
- or on demand when the executed program is the runtime linker itself,
  after it has loaded its target dynamic executable (see PRE(sys_mmapobj)),
  or when the first brk() syscall is made.

More preparatory work for ldsoexec support.

542fa886dc Initial data (brk) segment is setup on demand, when a first brk() syscall 
is made. It cannot be established during client image initialization because
that would conflict with a temporary stack which ld.so.1 (when executed directly)
uses for loading the target dynamic executable.
See PRE(sys_brk) in syswrap-solaris.c.

9b322bb026 Also install sigsegv handler in safe-pthread tests wrapper. 
In case we do recognize the xend, but detect it is invalid
(used outside a transaction) we generate a segsegv instead
of a sigill. Handle that in the same way in the test case.

This is just a testsuite cleanup. In the case defcfaexpr was compiled
with line number information (which might happen in some distro builds)
just throw it away because the expected output just wants to see the
function names.

b22d60778f Attempt to work around issues with xend being executed unconditionally 
when a pthread_rwlock is used in an invalid way.

Recent glibcs use transactional memory instructions to do lock ellision
but will sometimes, when locks are used in an invalid way, may calls to
xend on systems which don't support it, on the grounds that the program
is invalid anyway.

So we try and catch and ignore the resulting SIGILL in our tests that
deliberately work with invalid locks.
