[PATCH] Fix thread-safety for elfutils

[Heather McIntyre]

Hello all,

This patch was created to address thread-safety issues reported in bug 26921
<https://sourceware.org/bugzilla/show_bug.cgi?id=26921> and bug 26930
<https://sourceware.org/bugzilla/show_bug.cgi?id=26930>.
Additionally, other thread-safety fixes were applied during the process.

Brief Description:
Locking was implemented for tsearch and tfind.
Changes to multiple files within the libelf library were made such that
USE_LOCKS no longer causes tests to fail when enabled.
New tests were added to confirm thread-safety.

Please review the attached patch file and feel free to provide feedback. I
am available for any clarifications or modifications needed.

Best regards,
Heather McIntyre
