to meaningful value:
- When nfsdcnt is set, it dictates all values;
- Otherwise, nfsdargs.minthreads is set to user specified value, or the
automatically detected value if there is no one specified;
nfsdargs.maxthreads is set to the user specified value, or the value
of nfsdargs.minthreads if there is no one specified; when it is smaller
than nfsdargs.minthreads, the latter's value is always used.

Prior to this change pinning was implemented via an ioctl (VM_SET_PINNING)
that called 'sched_bind()' on behalf of the user thread.
The ULE implementation of 'sched_bind()' bumps up 'td_pinned' which in turn
runs afoul of the assertion '(td_pinned == 0)' in userret().
Using the cpuset affinity to implement pinning of the vcpu threads works with
both 4BSD and ULE schedulers and has the happy side-effect of getting rid
of a bunch of code in vmm.ko.

string by undefining __DATE__, since (unlike gcc) clang doesn't allow us
to do that. Instead, define NO_VERSION_DATE, which was helpfully added
to the named source code for exactly this purpose.
GZIP compressed manuals to appear in ./src instead of the appropriate obj dir.

The crunchide utility presumes the last 3 chunks of an ELF object
layout are section headers, symbol table, and then string table.
However, this is not specified in the ELF standards, and linkers
may generate different layouts when doing partial linking (-r).
This change is required to build FreeBSD with mclinker or the
gold linker.

If the MSI-table is located in the middle of a BAR then we will split the
BAR into two and create two mappings - one before the table and one after
the table - leaving a hole in place of the table so accesses to it can be
trapped and emulated.

devices are MSI-X capable. This in turn would lead it to treat bar 0 as
the MSI-X table bar even if the underlying device did not support MSI-X.
Fix this by providing an API to query the MSI-X table index of the emulated
device. If the underlying device does not support MSI-X then this API will
return -1.

Since ARP and routing are separated, "proxy only" entries
don't have any meaning, thus we don't need additional field
in sockaddr to pass SIN_PROXY flag.
New kernel is binary compatible with old tools, since sizes
of sockaddr_inarp and sockaddr_in match, and sa_family are
filled with same value.
The structure declaration is left for compatibility with
third party software, but in tree code no longer use it.

This uses the recently-added jemalloc(3) feature of setting the lg_chunk
tuning option to zero to request that memory be allocated in the smallest
chunks possible. Without this option, the default is to initally map 8MB,
and then the mlockall() call wires that entire allocation even though the
program only uses a few Kbytes of it at runtime.

break or only use the first one if they do) so using the first provider
by that name is a sufficient check. This also lets the scripted partitioner
install onto gmirror and geli and such things.
