man filesystems: move driver pages to section four

Filesystem manual pages describe drivers, not formats;
except for fs, which describes the structures of ffs/ufs,
not how to use it in the system.

tmpfs: increase memory reserve to a percent of available memory + swap

The tmpfs memory reserve defaulted to 4 MB, and other than that,
all of available memory + swap could be allocated to tmpfs files.
This was dangerous, as the page daemon attempts to keep some memory
free, using up swap, and then resulting in processes being killed.
Increase the reserve to a fraction of available memory + swap at
file system startup time. The limit is expressed as a percentage
of available memory + swap that can be used, and defaults to 95%.
The percentage can be changed via the vfs.tmpfs.memory_percent sysctl,
recomputing the reserve with the new percentage but the initial
available memory + swap. Note that the reserve can also be set
directly with an existing sysctl, ignoring the percentage. The
previous behavior can be specified by setting vfs.tmpfs.memory_percent
to 100.

Add sysctl for vfs.tmpfs.memory_percent and the pre-existing
vfs.tmpfs.memory_reserved to tmpfs(5).

Add extended attributes

The extattrs follows semantic of ufs, mean it cannot
be set to char/block devices and fifos. The attributes
are allocated using regular malloc with M_WAITOK
allocation with the own malloc tag M_TMPFSEA. The memory
consumed by extended attributes is limited to avoid OOM
triggereing by tmpfs_mount variable tm_ea_memory_max,
which is set initialy to 16 MB. The extended attributes
entries are stored as linked list in the tmpfs node.
The mount point lock is required only under setextattr
and deleteextattr to update extended attributes
memory-inuse counter, all other operations are doing
under vnode lock.
