Leverage the fact that OpenPGP cards use TLV encoding according to
ASN.1 BER-encoding rules and use sc_asn1_read_tag() as the workhorse
within pgp_enumerate_blob().
There's one peculiarity though:
OpenPGP cards expect 'cla' to be merged into 'tag'.
This is done manually after calling sc_asn1_read_tag().

Added:
* 00c4: new top-level DO in 2.0
can also be found inside constructed DOs 006E/0073 in 2.0 & 1.1
* 0101: new optional top-level DO starting in 1.1
for private use
max 254 bytes;
access: read - always; write - verify CHV2
* 0102: new optional top-level DO starting in 1.1
for private use
max 254 bytes;
access: read - always; write - verify CHV3
* 5f52: new top-level DO in 2.0
can also be found inside constructed DOs 006E in 2.0
* 7f21: new optional top-level DO in 2.0
use: card holder certificate (e.g. X.509) for the AUT key in the card
Removed:
* 0073: never a top-level DO, but part of top-level constructed DO 006E
Changed:
* 005e: not a constructed DO, but a simple/primitive DO
Note:
Trying to read non-existent top-level DOs or top-level DOs that weren't defined
in a spec version later than the current card's version does not hurt.
They are returned as empty.

* Correct naming: openpgp not opengpg
* Set the card name from ATR table
* Add card type enums
* Currently OpenPGP is read-only.

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). "

- Replace struct sc_atr_table / _sc_match_atr with
recently introduced _hex variants
- Rewrote _add_atr
- Introduce int type variable to sc_card_t, so that
every other card driver won't have to glue around
with this
- Card driver cleanups, optimize the number of
sc_match_atr called per card driver. Also
always try direct match with _sc_match_atr
first, before relying on eg. historical bytes
information on some card drivers
- Fixed a memory leak from the miocos driver
