Avoid running off into oblivion when a format string,
or arg to a %b conversion ends in an unescaped backslash.
Patch from Leo slightly modified by me.
compatibility with BIOC[GS]SEESENT ioctl. The userland interface is the same
as FreeBSD.
This change also fixes a bug that the direction is misunderstand on some
environment by passing the direction to bpf_mtap*() instead of checking
m->m_pkthdr.rcvif.
Rename local versions of getpwent getpwnam getpwnam_r getpwuid getpwuid_r
(all of the symbols are namespaced) in order to remove symbol clash with
libc.
This program uses code directly from libc.
As of today typical sanitizers require dynamic executables, while
crunchgen(1) programs are produced with static properties.
Lack of specified -s will:
- generate a Makefile file with NOSANITIZER=
- build programs that are dependencies with NOSANITIZER=
In future there is an option to handle sanitization in statically linked
programs.
An idea with -s LGTM by <christos>
These utilities (elf32, elf32_compat, elf64, liblldb) share code with the
ELF dynamic loader that is not being sanitized and its symbols are
installed into sanitized programs (in particular __tls_get_addr()).
Additionally libldd is used in rescue that is not expected to be sanitized
as of today.

Refactor the following code into something that is more clear
and fix signed integer shift, by casting all buf[] elements to
(unsigned int):
unsigned char buf[8];
uint32_t usize;
[...]
else {
usize = buf[4] | buf[5] << 8 |
buf[6] << 16 | buf[7] << 24;
[...]
New version:
usize = buf[4];
usize |= (unsigned int)buf[5] << 8;
usize |= (unsigned int)buf[6] << 16;
usize |= (unsigned int)buf[7] << 24;
Only the "<< 24" part needs explicit cast, but for consistency make the
integer promotion explicit and clear to a code reader.

assuming that it will be released by August 1, which is two months
from now. Thus I used 2018 dates for all holidays between Aug.
1st and Dec. 31st, and 2019 dates for all holidays between Jan.

this changes the upstream vendor from OpenSolaris to FreeBSD,
and this version is based on FreeBSD svn r315983.
in addition to the 10 years of improvements from upstream,
this version also has these NetBSD-specific enhancements:
- dtrace FBT probes can now be placed in kernel modules.
- ZFS now supports mmap().
that passing variables to recursive makes with :q works as expected.
- Revert :Q to work as before.
- Adjust makefiles that use recursive make to use :q

Ensure that the first database is correctly added when
more than one database is provided.
Fixes problem I introduced in rev 1.17 on 2009-04-12,
and noticed recently by Simon.
polling the job token pipe adds a lot of overhead
for little gain.
For now, just leave wantToken=0
And avoid busy waiting when no tokens are available and
no jobs are running.
