    add isc_buffer_constinit

			by Andrew Tridgell of the Samba project.) [RT #22629]

2988.	[experimental]	Added a "dlopen" DLZ driver, allowing the creation
			of external DLZ drivers that can be loaded as
			shared objects at runtime rather than linked with
			named.  Currently this is switched on via a
			compile-time option, "configure --with-dlz-dlopen".
			Note: the syntax for configuring DLZ zones
			is likely to be refined in future releases.

2987.	[func]		Improve ease of configuring TKEY/GSS updates by
			adding a "tkey-gssapi-keytab" option.  If set,
			updates will be allowed with any key matching
			a principal in the specified keytab file.
			"tkey-gssapi-credential" is no longer required
			and is expected to be deprecated.  (Contributed
			by Andrew Tridgell of the Samba project.)

			in the ISC__BUFFER_PUTUINT*() macros. [RT #592]

This is the basically the same change made to buffer.c before the macros
were created:

   revision 1.18
   date: 1999/09/23 17:54:57;  author: tale;  state: Exp;  lines: +4 -4
   Shut up MSVC++ compiler warning about loss of precision when assigning
   8 bits masked out of a 32 bit int to individual bytes.

Also, an #if 0 around "#define ISC_BUFFER_USEINLINE" was removed, per the
ISC coding style, and instead a comment was used to disable the definition.

own CVS tree will help minimize CVS conflicts.  Maybe not.
Blame Graff for getting me to trim all trailing whitespace.

Mostly, several functions that take pointers as arguments, almost
always char * pointers, had those pointers qualified with "const".
Those that returned pointers to previously const-qualified arguments
had their return values qualified as const.  Some structure members
were qualified as const to retain that attribute from the variables
from which they were assigned.

The macro DE_CONST was added to isc/util.h to deal with a handful of very
special places where something is qualified as const but really needs to have
its const qualifier removed.

Also cleaned up a few places where variable names clashed with reserved
identifiers.  (Which mostly works fine, but strictly speaking is undefined
by the standard.)

Minor other ISC style cleanups.

                        underscores were made to conform to the ANSI/ISO
                        standard, which says that such names are reserved.

Cleanup of redundant/useless header file inclusion.

ISC style lint, primarily for function declarations and standalone
comments -- ie, those that appear on a line without any code, which
should be written as follows:
   /*
    * This is a comment.
    */

Call the macros from within the compiled functions.  This puts the implementation in one place (buffer.h) and the REQUIRE() checking in buffer.c

                        Added:
                                isc_buffer_base(b)          (pointer)
                                isc_buffer_current(b)       (pointer)
                                isc_buffer_active(b)        (pointer)
                                isc_buffer_used(b)          (pointer)
                                isc_buffer_length(b)            (int)
                                isc_buffer_usedlength(b)        (int)
                                isc_buffer_consumedlength(b)    (int)
                                isc_buffer_remaininglength(b)   (int)
                                isc_buffer_activelength(b)      (int)
                                isc_buffer_availablelength(b)   (int)
                        Removed:
                                ISC_BUFFER_USEDCOUNT(b)
                                ISC_BUFFER_AVAILABLECOUNT(b)
                                isc_buffer_type(b)
                        Changed names:
                                isc_buffer_used(b, r) ->
                                        isc_buffer_usedregion(b, r)
                                isc_buffer_available(b, r) ->
                                        isc_buffer_available_region(b, r)
                                isc_buffer_consumed(b, r) ->
                                        isc_buffer_consumedregion(b, r)
                                isc_buffer_active(b, r) ->
                                        isc_buffer_activeregion(b, r)
                                isc_buffer_remaining(b, r) ->
                                        isc_buffer_remainingregion(b, r)

                        Buffer types were removed, so the ISC_BUFFERTYPE_*
                        macros are no more, and the type argument to
                        isc_buffer_init and isc_buffer_allocate were removed.
                        isc_buffer_putstr is now void (instead of isc_result_t)
                        and requires that the caller ensure that there
                        is enough available buffer space for the string.
