195aef9962 truss: Add support for utrace(2). 
This uses the kdump(1) utrace support code directly until a common library
is created.

This allows malloc(3) tracing with MALLOC_CONF=utrace:true and rtld tracing
with LD_UTRACE=1.  Unknown utrace(2) data is just printed as hex.

403ec61cbb Revert r288628 and instead fix a discrepancy between the posix_fadvise(2) 
man page and POSIX: posix_fadvise(2) returns an error number on failure.

4c60a05d25 - Move PF_LOCAL at the end of the array. PF_INET{,6} is used more often. 
- Add SOCKTYPE_ANY to PF_LOCAL.

- Apply AI_CANONNAME to only AF_INET{,6}.  It is not meaningful for the
  other AFs.

d358fa780b wordexp: Rewrite to make WRDE_NOCMD reliable. 
Shell syntax is too complicated to detect command substitution and unquoted
operators reliably without implementing much of sh's parser. Therefore, have
sh do this detection.

While changing sh's support anyway, also read input from a pipe instead of
arguments to avoid {ARG_MAX} limits and improve privacy, and output count
and length using 16 instead of 8 digits.

The basic concept is:
execl("/bin/sh", "sh", "-c", "freebsd_wordexp ${1:+\"$1\"} -f "$2",
    "", flags & WRDE_NOCMD ? "-p" : "", <pipe with words>);

The WRDE_BADCHAR error is still implemented in libc. POSIX requires us to
fail strings containing unquoted braces with code WRDE_BADCHAR. Since this
is normally not a syntax error in sh, there is still a need for checking
code in libc, we_check().

The new we_check() is an optimistic check that all the characters
  <newline> | & ; < > ( ) { }
are quoted. To avoid duplicating too much sh logic, such characters are
permitted when quoting characters are seen, even if the quoting characters
may themselves be quoted. This code reports all WRDE_BADCHAR errors; bad
characters that get past it and are a syntax error in sh return WRDE_SYNTAX.

Although many implementations of WRDE_NOCMD erroneously allow some command
substitutions (and ours even documented this), there appears to be code that
relies on its security (codesearch.debian.net shows quite a few uses).
Passing untrusted data to wordexp() still exposes a denial of service
possibility and a fairly large attack surface.

3caeab9db2 fnmatch(): Remove exponential behaviour as in sh r229201. 
The old code was exponential in the number of asterisks in the pattern.
However, once a match has been found upto the next asterisk, the previous
asterisks are no longer relevant.
