Subject: Revert "Add pretty printers for the NPTL lock types"

This reverts commit 62ce266b0b261def2c6329be9814ffdcc11964d6.

The change is not mature enough because it needs the following fixes:

1. Redirect test output to a file like other tests

2. Eliminate the need to use a .gdbinit because distributions will
   break without it.  I should have caught that but I was in too much
   of a hurry to get the patch in :/

3. Feature checking during configure to determine things like minimum
   required gdb version, python-pexpect version, etc. to make sure
   that tests work correctly.

-# The sed line replaces "@name@SOME_NAME@value@SOME_VALUE@" strings from the

-# The '-n' option, combined with the '/p' command, makes sed output only the
-# modified lines instead of the whole input file.  The output is redirected
-# to a .py file; we'll import it in the pretty printers file to read
-# the constants generated by gen-py-const.awk.
-# The regex has two capturing groups, for SOME_NAME and SOME_VALUE
-# respectively.  Notice SOME_VALUE may be prepended by a special character,
-# depending on the assembly syntax (e.g. immediates are prefixed by a '$'
-# in AT&T x86, and by a '#' in ARM).  We discard it using a complemented set
-# before the second capturing group.
