b7ff4d59de amd64: implement pagezero using rep stos
The current implementation uses non-temporal writes. This turns out to
be detrimental to performance if the page is used shortly after, which
is the typical case with page faults.

Switch to rep stos.

9c24291370 Fix up setgrent(3) to have a POSIX-compliant prototype.
Just like with freelocale(3), I haven't been able to find any piece of
code that actually makes use of this function's return value, both in
base and in ports. The reason for this is that FreeBSD seems to be the
only operating system to have such a prototype. This is why I'm deciding
to not use symbol versioning for this.

It does seem that the pw(8) utility depends on the function's typing and
already had a switch in place to toggle between the FreeBSD and POSIX
variant of this function. Clean this up by always expecting the POSIX
variant.

There is also a single port that has a couple of local declarations of
setgrent(3) that need to be patched up. This is in the process of being
fixed.

accdd12e71 [ar71xx_gpio] handle AR934x and QCA953x GPIO OE polarity.
For reasons I won't comment on, the AR934x and QCA953x GPIO_OE register
value is inverted - bit set == input, bit clear == output.

So, fix this in the output setting, in reading the initial state from
the boot loader, and also setting any gpiofunc pins that are necessary.

11c4989364 indent(1): Consistently indent declarations.
This fixes a very visible issue that may be hidden by some indent.pro
settings as in the example from FreeBSD's /usr/share.

From Piotr's log:
____
To prevent losing tabs from indentation in declarations, FreeBSD indent's
r125624 added code for the most common case when it's an identifier that
is indented, but didn't do anything with the original code that did the
same for any other cases. The other cases are: lparens (function pointer
declaration), asterisks (pointer declaration), stray semicolons, and
commas leading identifiers instead of trailing them.

Use the code added in r125624 (and improved in later commits) to write a
new function indent_declaration() and use it in all places that meant to
indent declarations. In order to indent only once per line, reuse existing
ps.dumped_decl_indent variable that was only used when formatting for
troff (-troff) until now.

869eb80c16 Both C99 and POSIX directly prohibits any standard function to set errno
to 0. Breaking this rule in 2001 NetBSD hack was imported which attempts
to workaround very limited glob() return codes amount. Use POSIX-compatible
workaround now with E2BIG which can't comes from other functions used
instead of prohibited 0.

aafbb33897 Improve boot loader quote parsing
parse() is the boot loader's interp_parse.c is too naive about quotes

both single and double quotes were allowed to be mixed, and single
quotes did not follow the usual semantics (re variable expansion).

The old code did not check for terminating quotes

This update implements:
 * distinguishing single and double quote
 * variable expansion will not be done inside single quote protected area
 * will preserve inner quote for values like "value 'some list'"
 * ending quote check.

this diff does not implement ending quote order check, it shouldn't
be too hard, needs some improvements on parser state machine.
