This makes the stapconf caching process quite a bit more transparent.
The options are now cached in a header file as #defines, and this header
file is a normal build dependency instead of calling so many make
$(shell ...) commands.
* buildrun.cxx (compile_pass): Pull in autoconf options in a header
of #defines rather than -DXXX, and make that header a build dependency.
* buildrun.cxx (output_autoconf): New function to consolidate the
computation of each autoconf test.
* cache.cxx (add_to_cache, get_from_cache, clean_cache): Start treating
the stapconf header as a first-class cached item.
* cache.h: Move definitions of things only needed in cache.cxx
* hash.cxx (find_stapconf_hash): Generate stapconf_name as a .h now.
* main.cxx (main): Default the stapconf_name based on getpid().

* tapsets.cxx: Major rework of dwflpp, dwarf_query, and related
code to make do with elf info if dwarf info is absent, or
(in the case of vmlinux) make do with a System.map-style
symbol table if even the elf file is absent.

--kmap, --ignore-vmlinux, and --ignore-dwarf.
* hash.cxx, session.h, stap.1.in: Added --kelf, --kmap,
--ignore-vmlinux, and --ignore-dwarf.

Even though the mkdtemp() man page indicates that the
directory will be created with always 0700 permissions,
it is actually affected by the process's umask.
So, if you run stap with an unusual umask it can end
up creating the temp dir with permissions that
staprun can't handle e.g.:
$> rpm -q systemtap
systemtap-0.6-1.fc9
$> umask 0122
$> stap -e 'probe begin { println("foo") exit() }'
ERROR: Error opening '/tmp/stapV4pBIb/stap_725b9bc541cef2618a5ccbc58bb64d15_287.ko': Permission denied
Obvious solution is to briefly set the umask to zero
in stap so as to ensure 0700 permissions.

* main.cxx: Restored pre-10-08 version: moved uprobes build to
buildrun.cxx.
* buildrun.cxx: Reworked uprobes build so that the resulting
Module.symvers can be used in building the stap-generated
module. If user isn't root, call verify_uprobes_uptodate()
rather than trying (and failing) to rebuild uprobes.ko.
* buildrun.h: uprobes_enabled() and make_uprobes() are no
longer extern.
* runtime/uprobes/Makefile: Added uprobes.ko target for use
by verify_uprobes_uptodate().
