dmsg - refactor cluster and pfs identifiers

LNK_CONN. Also remove pfs_mask and fs_label. Change cl_label to
peer_label. peer_label is now always a human-readonable string identifier
for the socket connection and no longer performs any connection filtering.
This allows it to be passed in LNK_SPANs to make the trees more
human-readable when dumped.

gcc50: Switch final specs to set DT_RUNPATH tag
The system dynamic binaries have always been built with DT_RPATH set

How it works is that when the linker is given the -rpath switch, it
will always set DT_RPATH, but if the --enable-new-dtags switch is present,
the linker will also set DT_RUNPATH tag. The dynamic linker reacts
differently when DT_RUNPATH is present; it will check LD_LIBRARY_PATH
before the rpath in that case.
This change (to gcc50 only) builds the system with the -rpath flag alone
by for the ctools compiler, but the final compiler's specs include the
--enable-new-dtags switch as well, which affects the building of ports and
all non-system use of the compiler.

sbin/hammer: Make hammer show properly print '*' for elements that match directive
- hammer show command (running with lo:objid directive specified)
goes back to normal iteration once it matches the directive as
explained in
e7f926a5, however it should not do 'search = NULL;'.
This commit adds a field btree_search::normal to do it right.
- The problem with 'search = NULL;' is that when there are many files
in a directory (e.g. dragonfly bsd source), different leaf nodes
of the same depth could happen to have inodes and dirents with the
same lo:objid. In this case it prints '*' only for matched records
located under the first leaf node because by the time it comes to
the second leaf node the pointer has been set to NULL and
NULL won't print '*' (see line 169 and 174 of cmd_show.c).
- In the following example it is expected that both leaf node 29
and 30 print '*' for its records that match
00000001:
00000001036af6f7,
but the result is it only prints for those under leaf node 29.

x86_64: Take advantage of ACPI/CPU specific C-state mapping
If BIOS maps shallow ACPI C-state (<C3) to deep CPU specific C-state
(>=C3), it implies no bus mastering operations are needed before
entering deep CPU specific C-states.

Looks like it is intentional to avoid bus mastering register
accessing, cache flush, and changing interrupt timer, which
is required for C3.

acpi/cstate: Match C-states of the hyperthreads on the same core
Some stupid BIOSes set different C-states for hyperthreads on the same
core, which prevents the core from entering deep C-states, since not
all hyperthreads of the core are in the deep C-states.
We fix this by using same number of C-states for hyperthreads on the
same core; the hyperthread w/ more C-states is taken as master.

kernel/acpi: Reduce code duplication with ACPICA (second attempt).
Use the types which the ACPICA framework provides whereever possible in
our acpi_fadt and acpi_madt code. Since we do not use any actual ACPICA
functions here, this is no problem even for code which (so far) runs
before ACPICA is initialized.
Compared to the previous attempt which I pushed (and reverted again)
this commit has the following additional fixes:
* Compare the FADT length to the length of the ACPI 2.0 (up to 4.0)
version of the table (which is 24 bytes shorter than the ACPI 5.0
version).
* Doesn't shift again an already shifted value.

of a sudden), but for now, this lowers the burden on log files.
