Teach indent(1) about storage-class specifiers. Don't assume
"in_parameter_declaration" state if "in_decl" hasn't been set. Don't set
"in_decl" for storage-class specifiers.
That set of changes helps with recognizing the difference between file
scope declarations like this:
static LIST_HEAD(, alq) ald_active;
static int ald_shuttingdown = 0;
struct thread *ald_thread;
and old style function declarators like this:
static int
do_execve(td, args, mac_p)
struct thread *td;
struct image_args *args;
struct mac *mac_p;
{
Unfortunately, at the same time this change makes indent(1) require
explicit int in declarations like "static a;", in order to understand that
it's part of a declaration. On the other hand, declarations like in the
first example are no longer indented as if ald_shuttingdown and ald_thread
were parameters of a function named LIST_HEAD.

This adds support to camcontrol(8) and libcam(3) for getting and setting
the time on SCSI protocol drives. This is more commonly found on tape
drives, but is a SPC (SCSI Primary Commands) command, and may be found
on any device that speaks SCSI.
The new camcontrol timestamp subcommand allows getting the current device
time or setting the time to the current system time or any arbitrary time.

buf_ring contains an assert that checks whether an item being
enqueued already exists on the ring. There is a subtle bug in
this assert. An item can be returned by a peek() function and
freed, and then the consumer thread can be preempted before
calling advance(). If this happens the item appears to still be
on the queue, but another thread may allocate the item from the
free pool and wind up trying to enqueue it again, causing the
assert to trigger incorrectly.
Fix this by skipping the head of the consumer's portion of the
ring, as this index is what will be returned by peek().

Prior to this change the loader self relocation code interpreted amd64's
rela relocations as if they were rel relocations, discarding the addend.
This "works" because GNU ld 2.17.50 stores the addend value in both the
r_addend field of the relocation (as expected) and at the target of the
relocation.
Other linkers, and possibly other versions of GNU ld, won't have this
behaviour, so interpret the relocations correctly.

pr_comment() did avoid adding surplus space character when a comment
contained it at the end. Now it's also paying attention to tabs.
Taken from: Piotr Stefaniak
indent.c has a special loop that stores tokens from between an if () and
the next statement into a buffer. The loop ignored all newlines, but that
resulted in not calling dump_line() when it was needed to produce the
final line of the buffered up comment.
Taken from: Piotr Stefaniak
Work-around a somewhat complex interaction within the code. From
Piotr's commit [1]:
When pr_comment() calls dump_line() for the first line of a multiline
comment, it doesn't include any indentation - it starts with the "/*".
This is consistent for both boxed and not boxed comments. Where the logic
diverges is in how it treats the rest of the lines of the comment. For box
comments indent assumes that it must not change anything, so lines are
dumped as they were, including the indentation where it exists. For the
rest of comments, it will first remove the indentation to store plain text
of the comment and then add it again where indent thinks it's appropriate
-- this is part of comment re-indenting process.
For continuations of multi-line comments, the code that handles comments
in dump_line() will use pad_output() to create indentation from the
beginning of the line (what indent calls the first column) and then write
string pointed by s_com afterwards. But if it's a box comment, the string
will include original indentation, unless it's the first line of the
comment. This is why tab characters from s_com have to be considered when
calculating how much padding is needed and the "while (*com_st == '\t')
com_st++, target += 8;" does that.
In dump_line(), /target/ is initially set to ps.com_col, so it always
assumes that indentation needs to be produced in this function, regardless
of which line of a box comment it is. But for the first line of a box
comment it is not true, so pr_comment() signals it by setting
ps.n_comment_delta, the negative comment delta, to a negative number which
is then added to /target/ in dump_line() on all lines except the first
one, so that the function produces adequate indentation in this special
case.
The bug was in how that negative offset was calculated: pr_comment() used
count_spaces() on in_buffer, which pr_comment() expected to contain
non-null terminated sequence of characters, originating from whatever
originally was on the left side of the comment. Understanding that
count_spaces() requires a string, pr_comment() temporarily set buf_ptr[-2]
to 0 in hope that it would nul-terminate the right thing in in_buffer and
calling count_spaces() would be safe and do the expected thing. This was
false whenever buf_ptr would point into save_com, an entirely different
char array than in_buffer.
The short-term fix is to recognize whether buf_ptr points into in_buffer
or save_com.

version but libc.so.7 had not been upgraded, and only provided
FBSD_1.4. I found I needed to update libc in order to run pkg, and I
also needed to use pkg to update libc... Which is why pkg-static
exists, but there's currently no way to tell the build system to use
pkg-static instead of pkg.
This creates a variable PKG_CMD, default value 'pkg', that can be
