cc4128c6b1 Add some FEATURE macros for various features (AUDIT/CAM/IPC/KTR/MAC/NFS/NTP/
PMC/SYSV/...).

No FreeBSD version bump, the userland application to query the features will
be committed last and can serve as an indication of the availablility if
needed.

76489ac1ea Use ISO C99 integer types in sys/kern where possible.
There are only about 100 occurences of the BSD-specific u_int*_t
datatypes in sys/kern. The ISO C99 integer types are used here more
often.

3b1bf8c2e9 Replaced the misleading uses of a historical artefact M_TRYWAIT with M_WAIT.
Removed dead code that assumed that M_TRYWAIT can return NULL; it's not true
since the advent of MBUMA.

There are ongoing disputes as to whether we want to switch to directly using
UMA flags M_WAITOK/M_NOWAIT for mbuf(9) allocation.

95727dd513 The "m = m->m_next" that was removed in the revision 1.12 was necessary
for the m->m_next != NULL case to avoid looping infinitely when the first
mbuf in the chain becomes full.

49e9cba72e Make m_getm() always return the top of the newly allocated chain, as
opposed to returning the top of the old chain when there was one and
the top of the newly allocated chain if there was no old chain.

Actually, it should be noted that prior to this fix, although the
comment above m_getm() advertised that m_getm() would return the
top of the old chain (if an old chain was being passed in) it
actually [wrongly] was returning the tail mbuf in the old chain
instead.  This is a bug but since the one use of m_getm() in
the tree luckily did not depend on the behavior, it happened
to work out without notice.

Harti Brandt pointed out that the advertised behavior was actually
not the real behavior and so this change makes m_getm() ALWAYS
return the newly allocated chain (and fixes the comment).  This
is less confusing and is the best course of action as then the
caller is always able to have both a reference to the top of
the original chain (because it's passing it in in the call) and
a reference to the newly attached chain.  Although the API is
slightly modified, I don't think that any third-party code uses
m_getm() and if it does, it surely can't be working properly
because the old behavior was bogus.

efdf333c00 Remove the hto(be|le)[slq] and (be|le)toh[slq] macros defined in
_KERNEL scope from "src/sys/sys/mchain.h".

Replace each occurrence of the above in _KERNEL scope with the
appropriate macro from the set of hto(be|le)(16|32|64) and
(be|le)toh(16|32|64) from "src/sys/sys/endian.h".

1cc1792ab5 Don't dereference the 'x' pointer if it is NULL, instead skip the
assignment.  The netsmb code likes to call these functions with a NULL
x argument a lot.

uses of iov_base which assume its type is `char *' (in order to do
pointer arithmetic) have been updated to cast iov_base to `char *'.
