p11cards are freed by emptying the virtual slots. virtual slots are
creatd with the framework's create_tokens. Hence, we need to free
p11card if no tokens were created.
I am using a somewhat modified version of IsoApplet. Up till now it worked fine. However recently I stumbled upon a web site that
forces a client cert auth with RSA-PSS. And (at least on windows, using minidriver) it didn't work. It looks to me, that it's a bug
in the PSS support code in minidriver, as I cannot find any place where a MGF1 padding scheme is specified. And since none is specified
signing fails. This patch fixes this. It assumes, that the same hash is used for hashing and padding.
This fixes a problem reported in Nitrokey forum at
https://support.nitrokey.com/t/veracrypt-encryption-with-nitrokey-error/2872
as inability to save the VeraCrypt's keyfile onto the token
after deleting an existing one, unless the PKCS11 is reinitialized.
Reason: commit cbc53b9 "OpenPGP: Support write certificate for Gnuk"
introduced a condition on getting the blob handle, which is surplus
(the pgp_find_blob() function actually does that) and prevents
the blob refresh upon deletion, breaking the logic introduced
earlier in commit 9e04ae4 and causing the higher-level effect reported.
While at it, corrected comments to actually reflect the flow logic.
Tested on Fedora 33 using the repro steps from the forum and Nitrokey Pro.

Option --use-locking has C_Initialize pass in parameters with the
CKF_OS_LOCKING_OK to tell module to use threads. The default is it passes NULL
which says threads are not needed.
The following is not designed to be used by the general user. There are for debugging
and test scripts and only compiled if the system has threads.
Option --test-threads <arg> can be passed multiple times. Each one starts a thread.
<arg> is a list of 2 byte commands seperated by ":". The thread will execute these.
Current commands are:
IN - C_Initialize(NULL)
IL - C_Initialize with CKF_OS_LOCKING_OK
Pn - Pause for n seconds
GI - C_GetInfo
SL - C_GetSlotList
Tn - C_GetTokenInfo from slot_index n
These are just enough calls to see if threads are working in the module.
Output is written to stderr.

While trying to setup an OpenSC context, the global_locking
and detect cards, it is possible that multiple threads may
call C_Initialize. The current code tries to prevent this using
"if (context == NULL)" but this is not a mutex, and
multiple threads may endup overwrite contexts and global locking and
cause additional problems, with pcsc and segfault.
FireFox appears to do this see #2032
The PR adds a mutex or Critical section to make sure only one
thread creates the context sets the global_locking and does
the initial detect cards, etc.
This allows the global_lock (if requested) to be setup
which is then used for other calls.
All but the first call to C_Initialize will return with CKR_OK,
others will return CKR_CRYPTOKI_ALREADY_INITIALIZED.

Changes to be committed:
modified: src/pkcs11/pkcs11-global.c
Fixes#2139
Added code to support mechanism GENERIC-SECRET-KEY-GEN.
Improved --help and doc/tools/pkcs11-tool.1.xml because key gen
of symmetric keys pass CKA_VALUE_LEN which is length of key in bytes.
Tested with:
./pkcs11-tool --module /usr/lib/x86_64-linux-gnu/softhsm/libsofthsm2.so \
--login --label generic-64 --keygen --key-type GENERIC:64 \
--mechanism GENERIC-SECRET-KEY-GEN
./pkcs11-tool --module /usr/lib/x86_64-linux-gnu/softhsm/libsofthsm2.so --login -O
