clang-analyzer complained that eqin() sets file-scoped pointer param_start
to point into char buffer defined in scan_profile(), and once
scan_profile() exits, param_start is a "dangling reference". param_start
was never used afterwards, but it's cleaner to move it to set_option()
which is the only branch where param_start is needed.

It's pr_comment.c that should decide whether to put a "star comment
continuation" or not. This duplicates code a bit, but it simplifies
pr_comment() at the same time since pr_comment() no longer has to "signal"
whether a star continuation is needed or not.
This change requires indent(1) to not wrap comment lines that lack a blank
character, but I think it's for the better if you look at cases when that
happens (mostly long URIs and file system paths, which arguably shouldn't
be wrapped).
It also fixes two bugs:
1. Cases where asterisk is a part of the comment's content (like in "*we*
are the champions") and happens to appear at the beginning of the line,
misleading dump_line() into thinking that this is part of the star comment
continuation, leading to misalignment.
2. Cases where blank starred lines had three too many characters on the
line when wrapped.

After a blank line was printed (to separate paragraphs in comments), the
next line was sometimes wrapped to the column at which the previous
non-empty line ended. The fix is to reset the last blank pointer (last_bl)
on newline.

Modify count_spaces() to take a third parameter "end" that will make the
function return when the end is reached. This lets the caller pass a
pointer to non nul-terminated sequence of characters. Rename
count_spaces() to count_spaces_until() and reinstate count_spaces(), this
time based on count_spaces_until().
Use count_spaces_until() to recalculate current column when going through
a comment just before the fragment which decides if current line of the
comment should be wrapped. This move simplifies this code by eliminating
the need for keeping the column counter up to date every time e_com is
advanced and also reduces spread of code that has to know how many columns
a tab will produce.
Deduplicate code that decided if a comment needs a blank line at the top.

The original indent(1) described unix-style comments as similar to box
comments, except the first non-blank character on each line is lined up
with the '*' of the "/*" which appears on a line by itself.
The code has been turned off for ages and -sc/-nsc make it even
less relevant.

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.

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.
No, this isn't a star trek science joke - sometimes LEDs are wired

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.

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.
