d6ed810a67 Perform conversions straight from the stream buffer instead of scanning
through byte by byte with mbrtowc(). In the usual case (buffer is big
enough to contain the multibyte character, character does not straddle
buffer boundary) this results in only one call to mbrtowc() for each
wide character read.

87275e436a Associate a multibyte conversion state object with each stream. Reset it
to the initial state when a stream is opened or seeked upon. Use the
stream's conversion state object instead of a freshly-zeroed one in
fgetwc(), fputwc() and ungetwc().

This is only a performance improvement for now, but it would also be
required in order to support state-dependent encodings.

b320e7fae7 For amd64, explicitly compile mcount.po, rather than copying mcount.o. We
need to compile it with -fno-omit-frame-pointers since the mcount code
depends on that, and by default it omits them without -pg.

5e44d7ebe1 Use conversion state objects to store the accumulated wide character,
low bound, and the number of bytes remaining instead of storing the
raw byte sequence and deriving them every time mbrtowc() is called.
This is much faster -- about twice as fast in some crude benchmarks.

857b57eae1 Remove a trailing newline, to behave as documented in syslog(3):
"A trailing newline is added if none is present."

The code in syslogd, stderr, and console output always adds a newline
at the EOL.  However, the existing code never actually removed a
trailing newline, and apparently relied on syslogd to convert it
into a space character.  Thus, the existing newline was converted
to a trailing space at the EOL by syslogd, while stderr, and console
output resulted in an empty line.

99ca5b8804 The FTS_NOSTAT option is an optimisation that reduces the number
of stat(2) calls by keeping an eye of the number of links a directory
has. It assumes that each subdirectory will have a hard link to its
parent, to represent the ".." node, and stops calling stat(2) when
all links are accounted for in a given directory.

This assumption is really only valid for UNIX-like filesystems: A
concrete example is NTFS. The NTFS "i-node" does contain a link
count, but most/all directories have a link count between 0 and 2
inclusive. The end result is that find on an NTFS volume won't
actually traverse the entire hierarchy of the directories passed
to it. (Those with a link count of two are not traversed at all)

The fix checks the "UFSness" of the filesystem before enabling the
optimisation.

757edc654e Add option NO_FP_LIBC, which disables floating-point support in
*printf() and *scanf().  Currently, this reduces the size of libc.so
by 9K on i386.  But the real savings are for static binaries that use
*printf() or *scanf() but not strtod(); with an FP-disabled libc,
these binaries will not depend on the gdtoa routines, making each
binary about 22K smaller.

8de9e89719 - To make it easier to compile *printf() and *scanf() without

  NO_FLOATING_POINT.
- Remove the HEXFLOAT option.  It saves an insignificant amount of
  space (<0.1% of the size of libc on i386) and complicates vfprintf()
  and checkfmt().

dbb4b1c83d Fix a bug that could result in getpw*() incorrectly returning NULL when NIS
adjunct maps are used.  One symtom of this bug is sshd saying:
	login_get_lastlog: Cannot find account for uid X

1cc11684ac MFdragonfly: resolver fix for timeouts on unqualified hostnames
res_search only incremented got_servfail for h_errno == TRY_AGAIN *AND*
  hp->rcode == SERVFAIL.  However, there are cases such as timeouts where
  rcode is not always set to SERVFAIL.  This leads to inconsistent nameserver
  operation during multi-domain and truncated dot searches, especially during
  booting when portions of the network are being brought up simultanious with
  dns lookups.

  This patch attempts to correct the problem by unconditionally terminating
  the search if TRY_AGAIN is returned (after res_query has gone through all
  retries and name servers) instead of trying other domain elements in the
  domain seach path.

  This patch should fix reported problems (which I can reproduce) with some
  NFS mounts failing during boot.  This occured because mount_nfs thought the
  host name lookup returned a definitive failure using a non-dotted host name
  when, in fact, it timed out on the first part (host.search.domain.name) and
  got a definitive host-not-found response on the second part (host.).

  Generally speaking, search path name server timeouts can exceed 60 seconds
  per element and most machines which consistently timeout on earlier portions
  of a search path are effectively non-operational due to the imposed delays.
  It is more important for DNS lookups to return the proper error code then
  to be able to recover a valid lookup in later portions of the search path
  in these situations.
