Add new function: suser(struct proc *), prototyped in <sys/proc.h>.
3:
s/suser_xxx(\([a-zA-Z0-9_]*\)->p_ucred, \&\1->p_acflag)/suser(\1)/
The remaining suser_xxx() calls will be scrutinized and dealt with
later.
There may be some unneeded #include <sys/cred.h>, but they are left
as an exercise for Bruce.
More changes to the suser() API will come along with the "jail" code.

Fixed problem with hanging while unmounting busy fs.
And (the most important) added some locks to prevent
simulaneous access to kernel structures!
cannot yet be closed, though.
I hope I got all credits right, and that the multiple submitted by lines
do not break anyone's scripts...

This can have bad security implications, but the impact on FreeBSD
systems is minimal because this fs isn't in the default kernels and it
is unknown if it even works.

Add d_parms() to {c,b}devsw[]. If non-NULL this function points to
a device routine that will properly fill in the specinfo structure.
vfs_subr.c's checkalias() supplies appropriate defaults. This change
should be fully backwards compatible with existing devices.

Prior to the removal, they were entirely unused.
c_caddr_t with extreme prejudice. Here we want to convert from
`const char *' to `const char *'. Casting through c_caddr_t is
not the way to do this. The original cast to caddr_t was apparently
to break warnings about const mismatches in other versions of BSD
(in 4.4BSDLite2, the conversion is from `const char *path' to
plain caddr_t).
changes to the VM system to support the new swapper, VM bug
fixes, several VM optimizations, and some additional revamping of the
VM code. The specific bug fixes will be documented with additional
forced commits. This commit is somewhat rough in regards to code
cleanup issues.

Don't write access time of a file more than once per day. (Its precision is
1 day anyway). Don't try to write access and creation time in nonwin95 case.

for possible buffer overflow problems. Replaced most sprintf()'s
with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.
These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.
