conformtest: split up running of tests from makefile.

This patch changes the logic by which header conformance tests are run
so that the makefiles run the tests for each (standard, header) pair
separately rather than as a single test (there are 518 such pairs
being tested at present).

Since these tests are slow and previously couldn't be run in parallel,
this obviously speeds up the whole test run significantly when using
parallel testing.  There are other benefits.  These tests can now be
marked as expected to fail at the level of (standard, header) pairs,
meaning that regressions introduced by a header change are much more
likely to be spotted (of course, such a regression could be a bug in
the header or in the expectations, most of which have not been
properly checked against the relevant standards).

The patch introduces lists in conform/Makefile of the headers to test
for each standard, with a new (quick) test for each standard that the
list agrees with the set of headers for which there are in fact
nonempty expectations for that standard.  This means that each of the
518 pairs being tested is actually something meaningful to test rather
than a null test.  I also hope to use these lists of headers in
various standards in future tests for namespace violations where a
function in a standard is implemented to call a non-reserved name for
a function outside that standard.

Although there are a lot of tests now marked as expected to fail, I
expect most of those to be easy to fix (whether with fixes to the
expectations, the headers or both - if fixing a header bug, of course
file it in Bugzilla first); only a limited number are likely to
reflect actual missing features in glibc.

Tested x86_64 (GCC 4.7 branch).  It's quite possible some failures
vary from platform to platform, in which case either additional XFAILs
can be added here, or platform-specific header bugs (if applicable)
the failures show up can be fixed.  I made XFAILs unconditional for
tests that should only fail for GCC 4.6 and earlier; we could make the
GCC version available in the makefiles and condition these, but simply
moving the XFAILing to a finer granularity seems a clear improvement
on the previous state of the whole of conformtest being XFAILed.
