9d09ecfa96 sigaction1: we need to remember if the sigcontext method may be useable, 
because libc can use it even if siginfo is available.

Changes are needed in libc to stop this being a performance penalty but
they will come later.

92ce8c6a3d Make the emulations, exec formats, coredump, NFS, and the NFS server 
into modules. By and large this commit:

- shuffles header files and ifdefs
- splits code out where necessary to be modular
- adds module glue for each of the components
- adds/replaces hooks for things that can be installed at runtime

e10fef6cd2 Split vfs out of rumpkern into rumpvfs. Non-fs rumps no longer 
include the file system code.  File system rumps explicitly need
to include rumpvfs from now on.

9e46e516a7 Move fd_closeexec() and fd_checkstd() from kern_descrip to their 
own file, subr_exec_fd.c (they're used only by exec).

After this change, the kernel source modules are in a partitioned
enough state to allow building a system without vfs at all.

2bae5b390e Some modules may want to avoid autounload because their use is transient. 
Their FINI routine may legitimately succeed even though the module is likely
to be used soon again, for example: exec_script. Add a MODULE_CMD_AUTOUNLOAD
to query whether a module wants to avoid autounload.

f94a8f9142 - Put modules that depend on others at the head of the queue so autounload 
can unload requisite modules with only one pass.

- If loading a requisite module, scan the global queue before checking the
  file system to see if it exists.  If it's already present we don't care.

355e64e949 Refact wapbl_replay_prescan to use a function for each WAPBL record. 
Merge wapbl_replay_get_inodes into wapbl_replay_prescan. Change the
logic to determine the head: It doesn't make sense to update it if the
last inode record seen was not the beginning of the journal, as the
beginning of the journal might not be 0, so always update inodeshead.

c42112239b In wapbl_replay_write just iterate over the hash table and not the 
transactions. The initial prescan has already sorted out what blocks are
in the journal and removed any revoced blocks, so the hash table is
authorative.

92a83dd9cf Backout revision 1.212 and add a comment that short-cutting the WAPBL 
case is not possible. The buffer length has changed and the rounded size
may not have, essentially changing the transaction size. Reported by
various users and in PR 39898.

9485f42356 - Local symbols could shadow globals in some instances. Fix it. 
- mutex_enter() from ksyms_getval() could panic due to a change made
  in revision 1.40. Fix it.

- Replace the p-tree with a binary search of global symbols. Saves about
  250kB of wired memory on i386 and allows for faster lookups within
  module symbol tables.
