Convert between elanid's and hostnames:
 int qsw_getnodeid_byhost(char *host);
 int qsw_gethost_bynodeid(char *host, int len, int elanid);

Send signal to all members of a program description (local operation):
 int qsw_signal_job(qsw_jobinfo_t jobinfo, int signum);

new path is ../../etc/slurm2.h

 o changed the order of some locking

Modified runqsw to config capability for localhost by default (was node 0).
Removed useless test code from qsw.c (most of this is covered in runqsw now).

Created new function to resync job bitmaps (if node table rebuilt).

	to DPCS with table cross-indecies).
Changed bit_fmt from bit-oriented function to word-oriented for
	dramatic performance improvement, especially with sparce
	bitmap.
Added function bitfmt2int to bits_bytes.c, builds integer array
	from output of bit_fmt for use by DPCS table scans.

Changed use of packstr everywhere (function redefined).

   null string otherwise
 o remove erroneous and unneeded #include <printf.h>

   are now macros that call the *mem functions
 o removed unneeded size argument from packstr

Converted packstr function to send string size as uint16_t (used to
	be uint32_t, which wasted space).

Modified src/api functions to build without warnings, mostly unused
	variables that were declared.
Changed un/packstr into separate unpackstr_ptr and unpackstr_xmalloc,
	the first returns a pointer into the buffer, the second allocates
	memory and copies the string into it.

 o include inittypes.h if available (for systems w/out stdint.h)

 o include stdint.h from pack.h (which seems to require the defs anyhow)
 o conditionally include config.h to allow other conditional includes
 o moved main() from pack.c over to testdir

 o keep qsw.h in HEADERS always

   to vsnprintf after expanding some simple and added cases. Fixes many
   things.

 o add qsw.c,h only if --with-elan specified

Added string pack/unpack functions and set of tests. - Jette

Restructured QSW side of API.

(program description, Elan hw contexts, etc.) for a parallel job.

to set size and magic in copy (since it is asserted to be correct in
source, it should be correct in destination after a memcpy).

qsw.c / qsw.h - beginnings of quadrics job initiation support library.
Very rough at this point!

Added definition of build_node_list for task distribution.
