Summary:
Migrate to using the semi-opaque type rman_res_t to specify rman resources. For
now, this is still compatible with u_long.
This is step one in migrating rman to use uintmax_t for resources instead of
u_long.
Going forward, this could feasibly be used to specify architecture-specific
definitions of resource ranges, rather than baking a specific integer type into
the API.
This change has been broken out to facilitate MFC'ing drivers back to 10 without
breaking ABI.

is followed by another structure (rr_schk) whose size must be set
in the schk_datalen field of the descriptor.
Not allocating the memory may cause other memory to be overwritten
(though dn_schk is 192 bytes and rr_schk only 12 so we may be lucky
and end up in the padding after the dn_schk).
This is a merge candidate for stable and 10.3

Several attempts to fix this logic was done after r241298, which were
all reverted, yet this change was not.
The .h file does not depend on the .c file, so do not impose such a
dependency on it. They are generated by the same command but do not
depend on each other. Restore the .ORDER which should handle parallel build
issues. This fixes an actual bug where the .h file is not recreated
when missing [1]. For example:
cd lib/libc
make cleanobj
make nsparser.h
rm nsparser.h
make nsparser.h # will not rebuild nsparser.h
I have been trying to track down a build problem where nsparser.h is
missing when nslexer.o is built. It is possible this is related.

This avoids reproducing the lex logic which had dependencies set wrong
and used an intermediate file for modifying the YY_BUF_SIZE.
This has only been possible since flex 2.5.37 was imported in r250873,
which uses #ifndef YY_BUF_SIZE.

DIRDEPS_BUILD does not yet support PROGS having their own dependency
file.
Overriding .MAKE.DEPENDFILE here causes major problems with the meta
mode logic since it creates the Makefile.depend as '.depend' resulting
in infinite loops in make due to dirdeps.mk including .depend endlessly.

For scripts using dialog(1) several times, it can be visually distracting
running dpv(1) several times amidst other dialogs. The `-k' option, similar
to dialog(1) `--keep-tite', enables the same functionality to smooth ti/te.
Similar to dialog(3) keep_tite option used to prevent visually disturbing
initialization or exit that could occur when run from a script using
dpv(3) by way of dpv(1) in sequence with other dialog(1) invocations.
A new sysdecode_syscallname() function accepts a system call code and
returns a string of the corresponding name (or NULL if the code is
unknown). To support different process ABIs, the new function accepts a
value from a new sysdecode_abi enum as its first argument to select the
ABI in use. Current ABIs supported include FREEBSD (native binaries),
FREEBSD32, LINUX, LINUX32, and CLOUDABI64. Note that not all ABIs are
supported by all platforms. In general, a given ABI is only supported
if a platform can execute binaries for that ABI.
To simplify the implementation, libsysdecode's build reuses the
existing pre-generated files from the kernel source tree rather than
duplicating new copies of said files during the build.
kdump(1) and truss(1) now use these functions to map system call
identifiers to names. For kdump(1), a new 'syscallname()' function
consolidates duplicated code from ktrsyscall() and ktrsyscallret().
The Linux ABI no longer requires custom handling for ktrsyscall() and
linux_ktrsyscall() has been removed as a result.

close or assert the bug that it is clear when leaving.
Remove an unrelated rotted comment that was attached to the buggy

Since draining is not done in more cases, flushing is needed in more
cases, so start fixing flushing:
- do a full flush in ttydisc_close(). State what POSIX requires more
clearly. This was missing ttydevsw_pktnotify() calls to tell the
devsw layer to flush. Hardware tty drivers don't actually flush
since they don't understand this API.
- fix 2 missing wakeups in tty_flush(). Most of the wakeups here are
unnecessary for last close. But ttydisc_close() did one of the
missing ones.
This flow control bug ameliorated the design bug of requiring
potentially unbounded waits in draining. Software flow control is the
easiest way to get an unbounded wait, and a long wait is sometimes
actually useful. Users can type the xoff character on the receiver
and (if ixon is set on the sender) expect the output to be held until
the user is ready for more.
Hardware flow control can also give the unbounded wait, and this bug
didn't affect hardware flow control. Unbounded waits from hardware
flow control take a more unusual configuration. E.g., a terminal
program that controls the modem status lines, or unplugging the cable
in a configuration where this doesn't break the connection.
The design bug is still ameliorated by a newer bug in draining for
last close -- the 1 second timeout. E.g., if the user types the
xoff character and the sender reaches last close, then output is
not resumed and the wait times out after just 1 second. This is
broken, but preferable to an unbounded wait. Before this change,
the output was resumed immediately and usually completed.
