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.

-# This script is a smaller version of the clever gen-asm-const.awk hack used to
-# generate ASM constants from .sym files.  We'll use this to generate constants
-# for Python pretty printers.
-#
-# The input to this script are .pysym files that look like:
-# #C_Preprocessor_Directive...
-# NAME1
-# NAME2 expression...
-#
-# A line giving just a name implies an expression consisting of just that name.
-# Comments start with '--'.
-#
-# The output of this script is a 'dummy' function containing 'asm' declarations
-# for each non-preprocessor line in the .pysym file.  The expression values
-# will appear as input operands to the 'asm' declaration.  For example, if we
-# have:
-#
-# /* header.h */
-# #define MACRO 42
-#
-# struct S {
-#     char c1;
-#     char c2;
-#     char c3;
-# };
-#
-# enum E {
-#     ZERO,
-#     ONE
-# };
-#
-# /* symbols.pysym */
-# #include <stddef.h>
-# #include "header.h"
-# -- This is a comment
-# MACRO
-# C3_OFFSET offsetof(struct S, c3)
-# E_ONE ONE
-#
-# the output will be:
-#
-# #include <stddef.h>
-# #include "header.h"
-# void dummy(void)
-# {
-#   asm ("@name@MACRO@value@%0@" : : "i" (MACRO));
-#   asm ("@name@C3_OFFSET@value@%0@" : : "i" (offsetof(struct S, c3)));
-#   asm ("@name@E_ONE@value@%0@" : : "i" (ONE));
-# }
-#
-# We'll later feed this output to gcc -S.  Since '-S' tells gcc to compile but
-# not assemble, gcc will output something like:
-#
-# dummy:
-# 	...
-# 	@name@MACRO@value@$42@
-# 	@name@C3_OFFSET@value@$2@
-# 	@name@E_ONE@value@$1@
-#
-# Finally, we can process that output to extract the constant values.
-# Notice gcc may prepend a special character such as '$' to each value.
-
-# found_symbol indicates whether we found a non-comment, non-preprocessor line.
-BEGIN { found_symbol = 0 }
-
-# C preprocessor directives go straight through.
-/^#/ { print; next; }
-
-# Skip comments.
-/--/ { next; }
-
-# Trim leading whitespace.
-{ sub(/^[[:blank:]]*/, ""); }
-
-# If we found a non-comment, non-preprocessor line, print the 'dummy' function
-# header.
-NF > 0 && !found_symbol {
-    print "void dummy(void)\n{";
-    found_symbol = 1;
-}
-
-# If the line contains just a name, duplicate it so we can use that name
-# as the value of the expression.
-NF == 1 { sub(/^.*$/, "& &"); }
-
-# If a line contains a name and an expression...
-NF > 1 {
-    name = $1;
-
-    # Remove any characters before the second field.
-    sub(/^[^[:blank:]]+[[:blank:]]+/, "");
-
-    # '$0' ends up being everything that appeared after the first field
-    # separator.
-    printf "  asm (\"@name@%s@value@%0@\" : : \"i\" (%s));\n", name, $0;
-}
-
-# Close the 'dummy' function.
-END { if (found_symbol) print "}"; }
