Convert to nmount. Add backwards compat cmount method. Same comment as msdosfs applies: It would be nice if we had generic option names for charset conversions. Use vfs_mountefrom(). Rely on vfs_mount.c calling VFS_STATFS().

Remove explicit calling of lockmgr() with the NULL argument. Now, lockmgr() function can only be called passing curthread and the KASSERT() is upgraded according with this. In order to support on-the-fly owner switching, the new function lockmgr_disown() has been introduced and gets used in BUF_KERNPROC(). KPI, so, results changed and FreeBSD version will be bumped soon. Differently from previous code, we assume idle thread cannot try to acquire the lockmgr as it cannot sleep, so loose the relative check[1] in BUF_KERNPROC(). Tested by: kris [1] kib asked for a KASSERT in the lockmgr_disown() about this condition, but after thinking at it, as this is a well known general rule, I found it not really necessary.

Cleanup lockmgr interface and exported KPI: - Remove the "thread" argument from the lockmgr() function as it is always curthread now - Axe lockcount() function as it is no longer used - Axe LOCKMGR_ASSERT() as it is bogus really and no currently used. Hopefully this will be soonly replaced by something suitable for it. - Remove the prototype for dumplockinfo() as the function is no longer present Addictionally: - Introduce a KASSERT() in lockstatus() in order to let it accept only curthread or NULL as they should only be passed - Do a little bit of style(9) cleanup on lockmgr.h KPI results heavilly broken by this change, so manpages and FreeBSD_version will be modified accordingly by further commits.
