The previous fix 192113552f did not
help, thus the new hypothesis is that PC/SC might return a valid
context with the value -1. We now use a dedicated flag to track the
validity of the context.
The reference counting seems to be superfluous and is a relict due to
backporting from 2.3. Removed.

Note that depending on the card backend (ccid or PC/SC) it might be
necessary to first send a reset followed by SERIALNO to get an updated
list of reader. Or well send KILLSCD.
The pretty printing of Assuan data lines does only work if you connect
direct to scdaemon because the wrapper in gpg-agent does not know
about this and combines the Assuan lines again.

A generated passphrase has enough entropy so that all kind of extra

if a passphrase has been generated (and not changed) and skip all
passphrase constraints checking.

This fixes a bug with user ids with leading spaces because:
wks-client lists all mail addresses from the key and matches them to the
requested mail address.
If there are several user-ids all with the same mail address
wks-client picks one of them and then extracts exactly that user id.
However, here it does not match by the mail address but by the full
user-id so that we can be sure that there will be only one user-id in
the final key.
The filter built expression unfortunately strips leading blanks but
requires a verbatim match. Thus it won't find the user id again and
errors out.
The new -t flag and a non-trimming strtokenize solves the problem.

That is actually a more correct directory than APPDATA. This fixes
a problem with installations where the APPDATA is non a network drive
and the resulting socket filename is truncated in our socket helper
function (because we use sockaddr also for our local socket
emulation on Windows).
LOCAL_APPDATA is expected to be on the local box and thus in the
majority of cases the resulting socket file name will be short enough.

Requirements for a passphrase to protect a private key and for a
passphrase used for symmetric encryption are different. Thus a
the use of a different pattern file will be useful. Note that a
pattern file can be used to replace the other passphrase constraints
options and thus we don't need to duplicate them for symmetric
encryption.

This implements the gpg-agent side for checking whether a new passphrase
entered by the user in pinentry satisfies the passphrase constraints.
Performing a checkpin inquiry is only allowed if the passphrase
constraints are enforced. setup_enforced_constraints sends necessary
options and translated strings to pinentry.
The patch also merges 557ddbde32 et
al. from master to add the genpin inquiry machinery.
The suggested passphrase has the required entropy of 128 bits.

--
Due to the unfortunate shutdown of the keyserver pool, the long term
defaults won't work anymore. Thus it is better to change them.
For https access keyserver.ubuntu.com is now used because it can be
expected that this server can stand the load from newer gnupg LTS
versions.
For http based access the Dutch Surfnet keyserver is used. However
due to a non-standard TLS certificate this server can not easily be
made the default for https.
Note: that the default server will be changed again as soon as a new
connected keyserver infrastructure has been established.
