* Add .Vt in the right places, transform some .Fa to .Vt, depending
on discussion context.
* When refering to the function malloc(), use .Fn, and not .Xr.
* Add `The' to prefix a sentence when describing a function, so
it results in ``The xxx() function..."
* Use `system call' instead of `syscall'.
* Improve the sentence which discusses accept_filt_generic_mod_event();
Talk about moduledata_t, and refer to the DECLARE_MODULE(9) manual
page.
* Properly markup .An (Author Name) throughout the AUTHORS section.
Added evil #define of ACCEPT_FILTER_MODULE to synopsis. Some of
the functions defined in this man page aren't declared unless
ACCEPT_FILTER_MOD is defined before including <sys/socketvar.h>.
