Remove extra debug that crept in

MFC: r287579

Implement pubkey support for the bootstrap

Note that to not interfer with finger print it expects a signature on pkg itself
which is named pkg.txz.pubkeysign

To genrate it:
echo -n "$(sha256 -q pkg.txz)" | openssl dgst -sha256 -sign /thekey \
-binary -out ./pkg.txz.pubkeysig

Note the "echo -n" which prevent signing the '\n' one would get otherwise

Instant-MFC r286933:

Issue warning and refuse to proceed further if the configured
repository signature_type is unsupported by bootstrap pkg(7).

Previously, when signature_type specified an unsupported method,
the bootstrap pkg(7) would proceed like when signature_type is
"none". MITM attackers may be able to use this vulnerability and
bypass validation and install their own versions of pkg(8).

At this time, only fingerprint and none are supported by the
bootstrap pkg(7).

FreeBSD's official pkg(8) repository uses the fingerprint method
and is therefore unaffected.

Errata candidate.

Fix bootstrapping pkgng by not appending "/latest/" to PACKAGESITE.

Reporter by : Alexander Yerenkow (via irc)

Add the ability to correctly read pkg.conf is exists.

Only look for boostrap useful options:
- PACKAGESITE
- ABI
- MIRROR_TYPE
- ASSUME_ALWAYS_YES

While here makes PACKAGESITE expand the ${ABI} variable.
Allow to deactivate any SRV record look up (MIRROR_TYPE=none)
Use the same mechanism as for pkgng itself: first get configuration out of
environment variable and fallback on pkg.conf if exists.

add usr.sbin/pkg which is a bootstrap tool for pkgng.
it respects PACKAGESITE, PACKAGEROOT, and a new environment variable ABI (if a user want to use a different API from the base one for its packages)
it has no man page on purpose to avoid hidding the pkg(8) man page from the pkgng package.
for now uses pkgbeta.FreeBSD.org as default mirror to find its package
it respects MK_PKGTOOLS
