Clean up FloatExceptionHandler elog message source code.

My analysis of the formerly mentioned IPC reinitialization problem was

Another PGINDENT run that changes variable indenting and case label indenting.  Also static variable indenting.

Fix pgproc names over 15 chars in output.  Add strNcpy() function.  remove some (void) casts that are unnecessary.

Various compile errors concerning overflow due to shifts, unsigned, and bad prototypes, from Solaris, from Diab Jerius

The following patches add to the backend a new debugging flag -K which prints
a debug trace of all locking operations on user relations (those with oid
greater than 20000). The code is compiled only if LOCK_MGR_DEBUG is defined,
so the patch should be harmless if not explicitly enabled.
I'm using the code to trace deadlock conditions caused by application queries
using the command "$POSTMASTER -D $PGDATA -o '-d 1 -K 1'.
The patches are for version 6.0 dated 970126.
