gpg: handle ASCII-armored keyrings as well 
gpg command "--list-keys" requires input files to be passed with
option "--keyring" and each file must match type "public keyring v4"
while gpg command "--show-keys" doesn't require extra options and
handles also ASCII-armored public keyrings as well.

Rework /dev, /sys, /proc mounting 
- assume all entries in @devfiles to be in /dev
 - allow for /dev, /sys and /proc not to exist in the target and print warning
 - allow for /dev entries as well as /sys and /proc not to exist on the outside
 - simplify umount by storing special options in @umountopts
 - remove superfluous checks for root and unshare mode
 - make sure /dev entries are less than 100 chars in size for tar

tarfilter: Compile prefix pattern only once 
According to Debian bug #978742, mmtarfilter has a slow performance with
many path exclusions. The execution can be speed up if the regular
expression is only compiled once instead of every time in the hot loop.

In root mode, check whether it's possible to mount 
- even if the user is root, they might not have permission to mount
 - check for CAP_SYS_ADMIN and unshare --mount before proceeding
 - allow one to disable the check with --skip=check/canmount
 - this is useful in container environments like docker

allow unshare as root user 
- this is useful when you are already root and want the benefits of
   unsharing the mount namespace to prevent messing up your system
 - if the unshare mode is used as root, the user namespace is not unshared
   anymore and newuidmap, setuid and friends are not called anymore
 - if the unshare mode is used as non-root test if the user namespace can be
   unshared, otherwise test if the mount namespace can be unshared

Optimize mmtarfilter to handle many path exclusions 
mmtarfilter uses fnmatch to handle path exclusions and inclusions.
Python's fnmatch handles shell patterns by translating them to regular
expressions, with a 256-entry LRU cache. With more than 256 path
exclusions or inclusions, this LRU cache no longer works, and every
invocation of fnmatch on every file in every package will re-translate
and re-compile a regular expression, resulting in much worse
performance.

Translate all the shell patterns to regular expressions once. For an
mmdebstrap invocation with around 500 path filters, this speeds up
mmdebstrap by more than a minute.
