Brad Barden 4dbd00fc94 mount: fix mount helper fs option handling 
If a mount helper is used, only argopts (given on commandline) are
passed to the helper via -o parameter. Option strings from fstab are
ignored.

This patch replaces global argopts pointer with a character array
fsopts. A maximum length for filesytem options is #defined (used by
fsopts and data), and argument/mntent options are length-checked to fit.
A filesystem with too long an option string will print an error, cause
mount to exit with an error status, and not attempt to mount the
filesystem. This obviates the need for overflow checking of data in
parseopts(), though it hasn't been removed.

Hiltjo Posthuma 71da5628d1 mount: helper support + improvements 
- helper support (mount.type).
  - helpers need to be in $PATH, if needed we can add a check for
    /sbin/mount.XXXX
  - pass -B, -M, -R to helper, its more reliable to pass these named
    options with -o however.
- allow prefix "no" for which type no action should be taken:
  mount -a -t nonfs,ext4

fix bugs:
- dont modify me->mnt_opts (used strtok).

Hiltjo Posthuma 710081b07a mount: change mounted() check 
- use getmntent_r instead of getmntent: because getmntent was nested it
  overwrote the previous internal mntent structure.
- check mounted() first, if not try to mount: this also makes sure filesystems
  were not mounted multiple times (like tmpfs) and errno is not overwritten in
  mounted(). For this reason also mount() errno EBUSY can't be used (tested).

Hiltjo Posthuma 7e394bd70f code-style: cleanup
