Debug Malloc (Dmalloc) Library Release Notes

Small feature and bug fix release. Fixed the Linux strdup problem and also rewrote the dmalloc utility internals a good bit.

The dmalloc utility will now look in the current directory for .dmallocrc before checking your $HOME directory.
Increased the internal storage of C filename sizes from 40 to 100 characters.

The dmalloc utility will now look in the current directory for .dmallocrc before checking your $HOME directory. This helps programmers have per-module specific dmalloc settings and controls.
Rewrote a significant portion of the internals of the dmalloc utility. It's processing of the RC files has been much improved.

Added USE_DMALLOC_LEAP variable which enables the library's leap functionality. The leap stuff allows you to disable the library by just linking in the libdmalloc_lp.a library instead of having to recompile your source files which included dmalloc.h. This was removed as a default feature since a poll on the dmalloc mailing list found few people aware of the feature and only one developer actually used it.

Added support for the PTHREAD_MUTEX_INITIALIZER define which is defined on some systems.

None.

Newer versions of Linux (6.X?) define strdup as a macro which was confusing prototypes in dmalloc.h. I added some specific autoconfiguration to handle this problem.
Increased the internal storage of C filename sizes from 40 to 100 characters.
In moving away from the leap substrate with the addition of the USE_DMALLOC_LEAP variable in the settings.dist file, this fixes a long standing bug with improperly tracking the first memory transaction -- usually an allocation. There was a chicken and egg problem with the way the library bootstrapped which has been resolved.
