We started generating gssapi_krb5.h from gssapi_krb5.hin when we
needed to use a 64-bit type for lucid contexts.  Since we can now
assume a standard name for 64-bit types, we can stop generating the
header.

Get rid of the caller parameter.  The kproplog semantics (without -R)
for mapping the ulog are simple and almost completely different from
other users of the ulog, so implement them as a static helper in
kproplog.  With hierarchical iprop, kpropd will need the same
semantics as FKCOMMAND and FKADMIND, which were already identical.

Get rid of the db_args parameter, since ulog_map no longer opens the
database after #7552.

Remove an inoperative lseek() call when creating a new ulog file.
Rename ulog_filesize to filesize and compute it from scratch each time
we use it, for easier analysis.  If kdb_hmagic is zero, init the ulog
header but don't skip the rest of the function; it's possible that we
need to expand the ulog file.  Remove an unneeded conditional before
calling extend_file_to for an existing ulog.

Make krb5_string_to_keysalts() default to only ":" as a key:salt
separator character.  Change most of its callers to pass NULL so they
get the default separators.

Adapted from a patch proposed by Jon Looney.

"kdb5_util use_mkey" should not require a kadmind restart to take
effect.  At the cost of fetching the K/M principal once for each key
change operation, make kadmind use the current active master key list
for each operation.

Add kadmin support for "addprinc -nokey", which creates a principal
with no keys, and "purgekeys -all", which deletes all keys from a
principal.  The KDC was modified by #7630 to support principals
without keys.

When we allocate space for an array of key_data structures, make sure
we allocate at least one, so we don't spuriously fail on platforms
where malloc(0) returns NULL.  Where we use malloc, use k5calloc
instead.  Where we use krb5_db_alloc or realloc, just allocate an
extra entry.

Wherever we use k5alloc with a multiplication in the size parameter,,
use the new k5calloc helper function instead.

Provide default values in pre.in for PROG_LIBPATH, PROG_RPATH,
SHLIB_DIRS, SHLIB_RDIRS, and STOBJLISTS so that they don't have to be
specified in the common case.  Rename KRB5_RUN_ENV and KRB5_RUN_VARS
to RUN_SETUP (already the most commonly used name) and RUN_VARS.  Make
sure to use DEFINES for local defines (not DEFS).  Remove some other
unnecessary makefile content.
