1. replaced all refs to bzero and bcopy to memset and memmove instead.
2. added a note to the CODING-GUIDELINES
3. add two macros to asterisk.h to prevent bzero, bcopy from creeping
back into the source
4. removed bzero from configure, configure.ac, autoconfig.h.in

This section covers some locking fundamentals, as well as some information on
locking as it is used in Asterisk. It describes some of the ways that are used
and could be used to achieve deadlock avoidance. It also demonstrates the
unfortunate conclusion that with the use of recursive locks, none of the
constructs in use today are failsafe from deadlocks. Finally, it makes some
recommendations for new code being written. As proper locking strategies is a
complex subject, this section still has room for expansion and improvement.
This is a result of collaboration between Luigi Rizzo and myself on the
asterisk-dev mailing list.

They want (char *)NULL as sentinel.
An example is OpenBSD (confirmed on 4.3) that ships with gcc 3.3.4
This commit introduces a contstant SENTINEL which is declared as:
#define SENTINEL ((char *)NULL)
All places I could test compile on my openbsd system are converted.
Update CODING-GUIDELINES to tell about this constant.

We do not longer approve "ThisEventOn" and "ThisEventOff" named events,
they need to be named "ThisEvent" with a status header showing the
current status.
(Approved by Mark)
Old events won't be changed to keep backwards compatibility,
until we have a revision plan for the AMI.

- Use a cleaner syntax for declaring the allocation macros
- Fix return value for ast_strdup/ast_strndup
- remove safe_strdup from app_macro, since ast_strup does the same thing
- fix a place in app_queue where ast_calloc+strncpy was used instead of
ast_strdup. If you are helping out with these conversions, please watch out
for other places where this is done.
- add a note to the coding guidelines about the fix to app_queue

add an automatically generated Asterisk log message if the allocation fails
for some reason. Otherwise, they are functionally the same, with the
exception of ast_strdup and ast_strndup. These functions have the added
ability to accept a NULL argument without error, which will just be ignored
without generating an error. The coding guidelines have also been updated to
reflect all of this information. (issue #4996)
