* Bootstrap llvm-tblgen and clang-tblgen with a minimal llvm static
library, that has no other dependencies.
* Roll up all separate llvm libraries into one big static libllvm.
* Similar for all separate clang and lldb static libraries.
* For all these libraries, generate their .inc files only once.
* Link all llvm tools (including extra) against the big libllvm.
* Link clang and clang-format against the big libllvm and libclang.
* Link lldb against the big libllvm, libclang and liblldb.
N.B.: This is work in progress, some details may still be missing.
It also heavily depends on bsd.*.mk's support for SRCS and DPSRCS with
relative pathnames, which apparently does not always work as expected.
For building llvm, clang and lldb though, it seems to work just fine.
The main idea behind this restructuring is maintainability and build
peformance. The previous large number of very small libraries, each
with their own generated files and dependencies was slow to traverse
and hard to understand.
Possible future improvements:
* Only build certain targets, e.g. for most regular users having just
one target will be fine. This will shave off some build time.
* Building the big llvm, clang and lldb libraries as shared (private)
libraries.
* Adding other components from the LLVM project, such as lld.

Now that we've switched over to using the vDSO on CloudABI, it becomes a
lot easier for us to phase out old features. System call numbering is no
longer something that's part of the ABI. It's fully based on names. As
long as the numbering used by the kernel and the vDSO is consistent
(which it always is), it's all right.
Let's put this to the test by removing a system call (thread_tcb_set())
that's already unused for quite some time now, but was only left intact
to serve as a placeholder. Sync in the new system call table that uses

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

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

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.

mkimg(1) uses a swap file to back input file chunks. When the output file
is being written out, blocks of the swap file are mapped and their contents
copied. This causes the backing VM pages to enter the active queue, and when
the output file is large relative to system memory (as is generally the
case), can result in a shortfall of inactive memory. This causes the
pagedaemon to aggressively scan the active queue and swap out process
memory in an attempt to meet the shortfall. Because mkimg's input files
are typically the intermediate result of some build process, there's no
need to push them all through the active queue. Use madvise(2) to indicate
that the backing pages may be reclaimed in preference to active pages. In
the case of the swap file, these pages will be freed as soon as mkimg
exits anyway.
When using mkimg on a desktop-class system with large amounts of dirty
process memory, this change substantially improves mkimg runtime and
reduces swap usage.

to ensure that the destination is NUL terminated. Length truncation
of one more character should not be an issue since encoding values
that long are not supported by libc. The destination string is
treated as a NUL terminated string, but it is only passed to strcmp()
for comparison to a set of shorter, fixed length strings, so this
is not a serious problem.

In the case where a file lacks a trailing newline, there is some "evil" code to
reverse goto the tokenizing code ("make_token") for the final token in the
file. In this case, 'fd' is closed more than once. Use a negative sentinel
value to guard close(2), preventing the double close.
Ideally, this code would be restructured to avoid this ugly construction.

Close the fd the poll error was detected on, rather than the last opened fd, to
fix the double-close.
Use -1 to make it explict which int variables no longer own socket file
descriptors.
Actually shrink, rather than grow, the poll timeout to match comment.

This logic was added to the whois() function in r281959, but could easily be
its own routine. In this case, I think the abstraction makes both functions
easier to reason about.
This precedes some Coverity-suggested cleanup.

Use size of destination buffer, rather than a constant that may or may not
correspond to the source buffer, to restrict the length of copied strings. In
particular, pr_fname has 16+1 characters but MAXCOMLEN is 18+1.
Use strlcpy instead of strncpy to ensure the result is nul-terminated. This
seems to be what is expected of these fields.

Simplify redundant malloc'ing in sed -e.
It is causing havoc in the ports tree:
===> Configuring for wxsvg-1.5.7
sed: 1: "/gcc_dir=\\`/s/gcc /$CC /": bad flag in substitute command: '/'
*** Error code 1
===> Patching for vips-8.3.1
sed: 1: "1s|^#![[:space:]]*/usr/ ...": bad flag in substitute command: 's'

When encountering an -e argument, sed currently mallocs a string to COPY
the optarg -- with '\n' appended. The appendage does not seem necessary --
indeed, the same call to add_compunit processing the sole command (given
without -e) passes the *argv verbatim: without making a copy, and without
appending newline.
This matches what is done in other BSDs.

Rewrite the main loop of the "sed s/..." command, shortening it by ten
lines and simplifying it by removing the switch statement implementing
/g, /1, and /2 separately and repetitively.
This will be needed to bring a fix from OpenBSD later.

Summary of changes:
- Replace all instances of FILES/TESTS with ${PACKAGE}FILES. This ensures that
namespacing is kept with FILES appropriately, and that this shouldn't need
to be repeated if the namespace changes -- only the definition of PACKAGE
needs to be changed
- Allow PACKAGE to be overridden by callers instead of forcing it to always be
`tests`. In the event we get to the point where things can be split up
enough in the base system, it would make more sense to group the tests
with the blocks they're a part of, e.g. byacc with byacc-tests, etc
- Remove PACKAGE definitions where possible, i.e. where FILES wasn't used
previously.
- Remove unnecessary TESTSPACKAGE definitions; this has been elided into
bsd.tests.mk
- Remove unnecessary BINDIRs used previously with ${PACKAGE}FILES;
${PACKAGE}FILESDIR is now automatically defined in bsd.test.mk.
- Fix installation of files under data/ subdirectories in lib/libc/tests/hash
and lib/libc/tests/net/getaddrinfo
- Remove unnecessary .include <bsd.own.mk>s (some opportunistic cleanup)
Document the proposed changes in share/examples/tests/tests/... via examples
so it's clear that ${PACKAGES}FILES is the suggested way forward in terms of
replacing FILES. share/mk/bsd.README didn't seem like the appropriate method
of communicating that info.
