* g10/trustdb.c (sanitize_regexp): Only escape operators.
--
Backport from master commit:
ccf3ba9208
To sanitize a regular expression, quoting by backslash should be only
done for defined characters. POSIX defines 12 characters including
dot and backslash.
Quoting other characters is wrong, in two ways; It may build an
operator like: \b, \s, \w when using GNU library. Case ignored match
doesn't work, because quoting lower letter means literally and no
much to upper letter.

For proper operations as a server we need to avoid global variables.
Thus we need to pass the session state CTRL to most functions. Quite
a lot of changes but fortunately straightforward to do.

* src/trustdb.c (check_regexp): Correctly print whether the
regexp matched or not.
--
This patch fixes the log message displayed when gpg attempts to
match the regexp associated with a trust signature with an user ID.
The current message interprets the 'ret' variable backwards, and
displays 'YES' when the regexp actually fails to match.

Signed-off-by: Neal H. Walfield <neal@g10code.com>
If the set of ultimately trusted keys changes, then it is possible
that a binding's effective policy changes. To deal with this, we
detect when the set of ultimately trusted keys changes and invalidate
all cached policies.
