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).

Added comments to an assortment of ther programs.

for DPCS.

Created new function to resync job bitmaps (when 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>

 o check for program_invocation_short_name

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

if they're present.

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. Updated src/test/pack-test.c
	accordingly.
Converted integers in various job/node/partition structures into
	uint32_t for ease of passing across network with API.

 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.
