Default to tracking .depend.* for OBJS rather than SRCS.
This helps cover some special case builds like gnu/lib/csu which
do more of a PROGS-like thing with bsd.prog.mk.
It is possible this causes out-of-tree Makefiles to have problems if they use
this pattern:
foo.o: foo.c
${CC} -o ${.TARGET} ${.ALLSRC}
This may cause multiple source files to be compiled due to finding the
'foo.o: foo.c' dependency both in the Makefile at the .depend file. Or
it may try compiling headers. This can be worked around by either of these:
foo.o: foo.c
${CC} -o ${.TARGET} ${.ALLSRC:N*.h:[1]}
Or
foo.o: foo.c
${CC} -o ${.TARGET} ${.CURDIR}/foo.c
In the latter case the ${.CURDIR} may need to be a different path. The
first case covers automatically using .PATH.

If a meta mode change is triggered but then the build fails then the
next build will not retrigger meta mode. This only prevented by
removing the target on rebuild or on the failure to rebuild.

This is in the case of not having any .depend.foo.o yet. Don't force add *.h
as a dependency for those. They are built in beforebuild already when in
SRCS/DPSRCS.
This change allows custom rules, like in bin/sh/Makefile for mksyntax, to not
have cyclic dependency problems when connected to the .depend.* handling.
This is purposely not copied to sys/conf/kern.post.mk as it handles
generating headers slightly differently.

asserted. Some development boards for example will reset on DTR,
and some radio interfaces will transmit on RTS.
This patch allows "stty -f /dev/ttyu9.init -rtsdtr" to prevent
RTS and DTR from being asserted on open(), allowing these devices
to be used without problems.

New sysctl/tunables can now set the interval (in seconds) between
rate-limited crypto warnings. The new sysctls are:
- kern.cryptodev_warn_interval for /dev/crypto
- net.inet.ipsec.crypto_warn_interval for IPsec
- kern.kgssapi_warn_interval for KGSSAPI

ccr depends on symbols exported by the cxgbe driver as well as having
a runtime dependency. While the runtime depenency was noted in the
manpage already, the compile-time dependency wasn't as clear.

Due to how the linker.hints file is laid out, we'll associate the pnp
info with the wrong module if the module declaration comes after the
pnp info. Until that limiation is removed, we need to have this
ordering. Ideally, we'd also enforce the ordering somehow, but I've
come up with no way to do that yet...

This is described in the vmem paper: "directs vmem to use the next free
segment after the one previously allocated." The implementation adds a
new boundary tag type, M_CURSOR, which is linked into the segment list
and precedes the segment following the previous M_NEXTFIT allocation.
The cursor is used to locate the next free segment satisfying the
allocation constraints.
This implementation isn't O(1) since busy tags aren't coalesced, and we
may potentially scan the entire segment list during an M_NEXTFIT
allocation.
