Instead of jumping out of the loop when the correct child is found,
and checking afterwards again if we found the correct object,
do everything directly in the loop and return from there.

martin 03381a2594 OpenPGP: re-factor pgp_enumerate_blob()
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

This is done manually after calling sc_asn1_read_tag().

ludovic.rousseau f47416d60e Do not cast the return value of malloc(3) and calloc(3)
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). "

aet 69d2e9014d - Optimize a few cpu cycles from _sc_match_atr_hex
- 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
