When processing loader.conf if console contained an entry for an unsupported
console then cons_set would return an error refusing to set any console.
This has two side effects:
1. Forth would throw a syntax error and stop processing loader.conf at that
point.
2. The value of console is ignored.
#1 Means other important loader.conf entries may not be processed, which is
clearly undesirable.
#2 Means the users preference for console aren't applied even if they did
contain valid options. Now we have support for multi boot paths from a
single image e.g. bios and efi mode the console preference needs to deal
with the need to set preference for more than one source.
Fix this by:
* Returning CMD_OK where possible from cons_set.
* Allowing set with at least one valid console to proceed.

EFI was mixing caching in two separate places causing issues when multiple
partitions where tested.
Eliminate this by removing fsstat and re-factoring fsread into fsread_size,
adding basic parameter validation.
Also:
* Enhance some error print outs.
* Fix compilation under UFS1_ONLY and UFS2_ONLY
* Use sizeof on vars instead of structs.
* Add basic parameter validation to fsread_size.

In r55943, a per-process queue of pending socket AIO requests (requests
waiting for the socket to become ready) was added so that they could be
cancelled during process rundown. In r154765, the rundown code was
changed to handle jobs in this state (JOBST_JOBQSOCK) directly removing
the need for the extra queue. However, the per-process queue head and
global lock were never removed.

2. increment numneg after new entry is added
No functional changes.
No objections: kib
Previously the code would just increment statistics while only holding a
shared lock, in effect losing updates.
Separate tracking for nchstats is removed as values can be obtained from
existing counters. Note that some fields are updated by external
consumers and are left unfixed. This should not be a serious issue as
this structure looks quite obsolete.
No strong objections: kib
a) Look for the CPL in the payload buffer instead of the descriptor.
b) Retrieve the socket associated with the tid with the inpcb lock held.
