New version of pcsc-lite: 1.8.0

I just released new version of pcsc-lite 1.8.0.

Changes:
pcsc-lite-1.8.0: Ludovic Rousseau
19 November 2011

• PC/SC spy tool. See "PCSC API spy, third try"
• Support systemd socket activation (the auto start of pcscd from the library has been removed. Use systemd instead). See "pcscd auto start using systemd"
• SCardGetStatusChange(): check all the readers are already known and return SCARD_E_UNKNOWN_READER if a reader name is not present. Windows XP has this behavior.
• SCardEstablishContext(): Invalidate all the handles in the son after a fork
• Add define of FEATURE_EXECUTE_PACE from PCSC v2 Part 10 Amendment 1 2011-06-03
• Fix some memory leaks reported by Coverity
• Enable silent build by default
• log_line(): correctly calculate delta time when no color is used The update of last_time was only done in case of colorization (LogDoColor). So on unsupported consoles the time was wrong.
• log_xxd_always(): Use a variable-length array The debug message buffer is no more with a fixed size (around 600
  bytes of buffer to log) but uses a variable-length array. It is now possible to log extended APDU of 64kB.
  The variable-length array feature is available in GCC in C90 mode and is mandatory in C99 standard.
• Some other minor improvements and bug corrections
