"CHANGE REFERENCE DATA" (PIN change) and "RESET RETRY COUNTER"
(PIN unblock) commands in OpenPGP card have various limitations.
These also depend on whether the card is version 1.x or 2.x.
Provide helpful debug messages for user in case he is trying to do
a PIN command in a way that isn't supported by the card.
Also, take into account that version 2.x cards don't support references to
PW1-mode 2 (82) in these commands - change them to PW1 (81).

According to descriptions of commands "PSO: COMPUTE DIGITAL SIGNATURE",
"PSO: DECIPHER" and "INTERNAL AUTHENTICATE" in OpenPGP card spec (versions
1.1 and 2.1.1) the card adds / strips and checks PKCS#1 padding
automatically.
There is no documented way to perform raw RSA operations on this card so
SC_ALGORITHM_RSA_RAW flag shouldn't be set.

Basically checks that the memory allocation succeed.
The ctbcs.c change improve the readability
because count = 0 and len > 254 does not add any value.
VTA: added few coding style changes
In old implementation, the DOs which their access is restricted by
PIN (like DOs 0101 -> 0104) were excluded from the fake filesystem,
leading to that we cannot read their data later, even if we verified PIN.
If tlvblock is not stored then the value is lost and the allocated
mempry is leaked.
Coverity: Resource leak (RESOURCE_LEAK)
Calling allocation function "pgp_build_tlv" on "tlvblock".
The card contains only 1 certificate, which can be used for encrypting.
But this certificate is bound with authentication key, so when decrypting,
the authentication key will be presented to check.
This commit allows to bypass the check in driver. However, it is not enough.
The users have to import the same key to "Encryption key" to help the card find
right key to work.
OpenPGP: Add log and comments.
OpenPGP: Pretend to select dummy files.
Some files are needed by pkcs15init, but not exist in OpenPGP card.
We pretend to know these dummy files to make pkcs15init successful.
Compilation error on windows:

* use LOG_FUNC_CALLED() .. LOG_FUNC_RETURN for "symmetric" logging
* don't zero-fill the DO's contents but empty it
* get rid of unnecessary variables
* select parent DF after deletion (required by to ISO 7816-9)
* don't try to delete MF
Fail on idx > 0 in order to avoid the requirement to read from the DO.
The DO may be read-protected, and this might either fail or produce
wrong results.
* use LOG_FUNC_CALLED() .. LOG_FUNC_RETURN for "symmetric" logging
* update comment
* check that blob->data is defined
* fix writing new data to the correct offset
* use calloc() instead of malloc() & memset()
* align pgp_ops function pointer list
* make sure variables of type u8 do only get passed fitting data
* use LOG_FUNC_CALLED() .. LOG_FUNC_RETURN for "symmetric" logging
* leave most of the spcial casing in ADPU handling to sc_adpu_transmit()
* use SC_ADPU_CASE_1 for empty buffer (avoids special casing Lc=0)
* clean up log strings & comments
Replace the "one-trick-pony" pgp_do_iswritable() with a more generic
function returning the blob matching the passed tag.
This way we can get rid of the one-line function pgp_blob_iswritable() too.
comparisons like these can be done in the caller.
Set pin references to 0x01 - 0x03 instead of 0x81 - 0x83.
The PINs are referenced as PIN1- PIN3 (resp. PW1 - PW3) in the OpenPGP
card specification.
Technically the APDUs to verify/change the PINs contain the values OR-ed
with 0x80, but this is just a technical detail of the implementation
which the emulated file system can hide in pgp_pin_cmd().
Pros & Cons:
+ consistent PIN naming
+ no trouble entering the correct PIN names in opensc-explorer et.al.
("verify CHV1" is way better than "verify CHV129")
- manually entering the correct APDU for VERIFY is a bit more complex.
(who does this anyway, when there are better functions)
While at it, change if .. elsif ... cascade to switch statement.
* parse more extened capabilities & features into a private enum
* for v2.0 cards, always parse the "historical bytes" DO
reason: ATR may be static and thus cannot reflect the state
Remove links pointing to the blob to be deleted from other blobs in the
blob tree structure, so that removing a subordinate blob does not hurt
its parent or siblings.

From http://en.wikipedia.org/wiki/Malloc#Casting_and_type_safety
" Casting and type safety
malloc returns a void pointer (void *), which indicates that it is a
pointer to a region of unknown data type. One may "cast" (see type
conversion) this pointer to a specific type, as in
int *ptr = (int*)malloc(10 * sizeof (int));
When using C, this is considered bad practice; it is redundant under the
C standard. Moreover, putting in a cast may mask failure to include the
header stdlib.h, in which the prototype for malloc is found. In the
absence of a prototype for malloc, the C compiler will assume that
malloc returns an int, and will issue a warning in a context such as the
above, provided the error is not masked by a cast. On certain
architectures and data models (such as LP64 on 64 bit systems, where
long and pointers are 64 bit and int is 32 bit), this error can actually
result in undefined behavior, as the implicitly declared malloc returns
a 32 bit value whereas the actually defined function returns a 64 bit
value. Depending on calling conventions and memory layout, this may
result in stack smashing.
The returned pointer need not be explicitly cast to a more specific
pointer type, since ANSI C defines an implicit conversion between the
void pointer type and other pointers to objects. An explicit cast of
malloc's return value is sometimes performed because malloc originally
returned a char *, but this cast is unnecessary in standard C
code.[4][5] Omitting the cast, however, creates an incompatibility with
C++, which does require it.
The lack of a specific pointer type returned from malloc is type-unsafe
behaviour: malloc allocates based on byte count but not on type. This
distinguishes it from the C++ new operator that returns a pointer whose
type relies on the operand. (see C Type Safety). "
