The shquote() and shquotev() functions copy strings and transform the
copies by adding shell escape and quoting characters. They are used to
encapsulate arguments to be included in command strings passed to the
system() and popen() functions, so that the arguments will have the cor-
rect values after being evaluated by the shell.

used to syslog and also send to stderr).
This behaviour can be changed by setting $LIBC_DIAGASSERT to a
string containing one or more of the following letters:
a abort() after syslog and/or print to stderr
A opposite of a
e print assertion message to stderr
E opposite of e
l log assertion message to syslog
L opposite of l
This allows per-process control of the _DIAGASSERT() behaviour (e.g,
if you want to abort() after the assertion is raised) by modifying the
environment before starting the process.
Note that __DIAGASSERT() is still a no-op unless libc is compiled
with -D_DIAGNOSTIC.
* Implement __assert()/__diagassert() by calling __assert13()/__diagassert13()
with a function of NULL, reducing unnecessary code duplication
the argument, instead of va_list. Might not make a difference on most
ports, depending on toolchain/MD typedefs. Does make a difference on sparc64,
where it wouldn't compile otherwise.
- keep the case consistent between the actual name and what's referenced.
e.g, if it's `foo', don't use '.Nm Foo' at the start of a sentence.
- remove unnecessary `.Nm foo' after the first occurrence (except for
using `.Nm ""' if there's stuff following, or for the 2nd and so on
occurrences in a SYNOPSIS

libc minor bump for new API entry point.
If an argument of a ctype function is outside "unsigned char"
and if it is not EOF, the behavior is undefined.
The isascii(3) is the sole exception of above and it was used to
be used to check a value was valid for other ctype functions in
ancient systems. On modern systems, the ctype functions take
all values of "unsigned char", and this check is obsolete and
even wrong for non-ASCII systems. However, we leave the isascii()
untouched for now, so as not to change the current behavior.
struct dirent *, rather than non-const. this makes scandir(3) the
same as the scandir implementations in libiberty and glibc, and the
select function has no need to modify the dirent.
AF_INET6 wildcard listening socket. heavily documented in ip6(4).
net.inet6.ip6.bindv6only defines default value. default is 1.
"options INET6_BINDV6ONLY" removes any code fragment that supports
IPV6_BINDV6ONLY == 0 case (not defopt'ed as use of this is rare).
this allows you to disable/enable ICMPv6 node information query/reply
processing (which tells remote end the gethostname(3) setting, interface
addresses on the node, and some other things - documented in
draft-ietf-ipngwg-icmp-name-lookup* or something alike).
to test it, try ping6 -w ::1 with nodeinfo=0 and nodeinfo=1.
(sync with kame change)
On platforms where we can use weak aliases, use
__weak_alias(__errno, __errno_func);
and on platforms where we cannot, just compile the function as
__errno, since on those platforms we cannot make libc thread-safe,
at least using this trick.
Are there any platforms where we cannot do __weak_alias() anymore?
* sl_add(); if realloc() fails return -1 instead of calling err(1,...).
otherwise, return 0.
NOTE: this change resulted in sl_add() changing from returning void to int.
this shouldn't be a problem because a) it returns 0 if ok (aka `void', b)
all invokers of sl_add() in the tree have been changed (mainly code i've
written).

svis(char *dst, int c, int flag, int nextc, const char *extra);
int
strsvis(char *dst, const char *src, int flag, const char *extra);
int
strsvisx(char *dst, const char *src, size_t len, int flag,
const char *extra);
These functions correspond to vis(), strvis(), and strvisx() but have an
additional argument extra, pointing to a NUL terminated list of characters.
These characters will be copied encoded or backslash-escaped into dst. These
functions are useful e. g. to remove the special meaning of certain
characters to shells.
To implement the new functions, vis underwent a major rewrite. Most functions
now use a central macro, SVIS. Performance increase ~ factor 2.

* There was an off-by-one error that caused the addition of a NUL or slash in fts_build() to
overwrite other memory.
* After fts_palloc(), we need to reset `cp' so that it points to the new path name buffer;
otherwise the addition of the file name before calling fts_stat() could lose.
Also, fix stupidity in the fts_palloc() interface. We don't want N bytes more than the
current buffer size; we want N bytes more than the current length. Just pass in the new
size, since we can't figure it out easily here.
