instead of manual zeroing of the debug registers file in pcb.
This centralizes the cleaning code, but the practical difference is
that PCB_DBREGS flag is cleared, saving some operations on context
switching.

Due to how we're parsing UUIDs, we were disallowing setting, printing or
deleting any UEFI variable with a '-' in it when you attempted to do that
operation with the exact name (wildcard reporting was unaffected). Fix the
parser to loop over all the dashes in the name and only give up when all
possible matches are exhausted.

This fixes a regression in d36d681615, where the call to
__tls_get_address() was performed under rtld_bind_lock write-locked.
Instead use tls_get_addr_slow() directly, with locked = true.

The intent is to better handle time intervals with large amount of RIB
updates (e.g. BGP peer going up or down), while still keeping low sync
delay for the rest scenarios.
The implementation is the following: updates are bucketed into the
buckets of size 50ms. If the number of updates within a current bucket
exceeds the threshold of 500 routes/sec (e.g. 10 updates per bucket
interval), the update is delayed for another 50ms. This can be repeated
until the maximum update delay (1 sec) is reached.
All 3 variables are runtime tunables:
* net.route.algo.fib_max_sync_delay_ms: 1000
* net.route.algo.bucket_change_threshold_rate: 500
* net.route.algo.bucket_time_ms: 50

Because of that some window sizes were silently demoted to 0 and ignored.
Check the size if its too large, trim it to 4GB and print a warning message.

Recent testing of network partitioning a FreeBSD NFSv4.1
server from a Linux NFSv4.1 client identified problems
with both the FreeBSD server and Linux client.
The FreeBSD server failec to reply using the cached
reply in the session slot when an RPC was retried on
the session slot, as indicated by same slot sequence#.
This patch fixes this. It should also fix a similar
failure for NFSv4.0 mounts, when the sequence# in
the open/lock_owner requires a reply be done from
an entry locked into the DRC.
This fix affects the fairly rare case where a NFSv4
client retries a non-idempotent RPC, such as a lock
operation. Note that retries only occur after the
client has needed to create a new TCP connection.
