Add missing prototypes.

Cleanup:

- Add $DragonFly$.
- Ansify function definitions.
- Change pmap_set()'s 'port' parameter from int to u_short.
- In function definitions, move the type on a line of its own.
- Remove (void)

Update libedit from NetBSD.

libedit update by: Ben Woolley <tautolog@gmail.com>

Add missing atoll.

Introduce pthread_timedjoin_np.

Add declaration of struct tm to suppress a warning.

Pull in sys/types.h if it has not been parsed yet.

Fix strmode()'s parameters to reflect the reality it had been in for a long
time.

Tripped by over: ANSI C conversion and Michael Ray

Reflect type change and remove third clause.

Too many windhills in the third party software world to fight them all.
Maybe programmers learn once not to mess with namespaces, but capitulate
for now and prefix the ctype masks with _CTYPEMASK.

Add strnvis, which is orthogonal to strvisx by bounding dst, not src.

Sync with FreeBSD HEAD.

Add real function versions of the _unlocked family. Use putc for putchar
directly.

Smoke something else and revert the use of ssize_t, I've put it there
for a reason after all.

Remove space before '('. Correctly align some function names. No need to
use local versions of ssize_t (size_t is used already) or const.

Make struct dirent contain a full 64bit inode. Allow more than 255 byte
filenames by increasing d_namlen to 16bit. Remove UFS specific macros

Make struct dirent contain a full 64bit inode. Allow more than 255 byte
filenames by increasing d_namlen to 16bit. Remove UFS specific macros
from sys/dirent.h, programs which really need them should include
vfs/ufs/dir.h. MAXNAMLEN should not be used, but replaced by NAME_MAX.

To keep the impact for older BSD code small, d_ino and d_fileno are kept
in the old meaning when __BSD_VISIBLE is defined, otherwise the POSIX
version d_ino is used. This will be changed later to always define only
d_ino and make d_fileno a compatiblity macro for __BSD_VISIBLE.

d_name is left with hard-coded 256 byte space, this will be changed at
some point in the future and doesn't affect the ABI. Programs should
correctly allocate space themselve, since the maximum directory entry
length can be > 256 byte.

For allocating dirents (e.g. for readdir_r), _DIRENT_RECLEN and
_DIRENT_DIRSIZ should be used. NetBSD has choosen the same names.
Revamp the compatibility code to always use a local kernel buffer and
write out the entries. This will be changed later by passing down the
output function to vop_readdir, elimininating the redundant copy.

Change NFS and CD9660 to use to use vop_write_dirent, for CD9660 ensure
that the buffers are big enough by prepending char arrays of the right
size.

Don't define infinite macros when we want to define infinity.

Add wcsftime(3).

If possible, use builtin constants for newer GCC versions, but fallback
to libc variables otherwise. Add support for C99 comparision macros,
using the builtins when available.
