"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.

- bug fix: re-initialize index to start searching at the right place
- get rid of unnecessary variable
- add some line breaks & comemnts for easier understanding
- get rid of unnecessary variable
- use easily understandable hex representation of APDUs
- auto-calculate APDU length based on hex representation
- restrict scope of some variables
- use sc_log() instead of directly writing to console
- line breaks & comments for easier reading/understanding
- fix typo in log message
- 2 line breaks between functions for easier reading
- function type on separate line
- mark each function as 'ABI' or 'Internal'
- slightly doxygen-ize comments introducing functions
- fix typos in comments
- break over-long comment lines
- break comment lines at sensible places
- consistent calling style for DRVDATA()
- no code change
- get rid of unnecessary variables
- use for-loop to initialize/check/increase run variable in one place
- restrict variables to the necessary scope
- use ternary operator inside a statement instead of if...else...
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.
