f5016d88dd Prevent undefined behavior 
Don't call XMEMCPY() in case info (the source parameter to memcpy) is NULL

7db5760c91 add possibility to create combined coverage 
Define the environment variable LTC_COVERAGE to something, run testme.sh
with all the coverage compile time options enabled and then 'make lcov'
creates the combined coverage for all combinations of compile-time
options handled in testme.sh.

e.g. LTC_COVERAGE=1 ./testme.sh "makefile -j3" "-DUSE_LTM -DLTM_DESC -I../libtommath -fprofile-arcs -ftest-coverage" "../libtommath/libtommath.a -lgcov"

75b114517a make sure no cache-based timing attack is possible 
instead of two different buffers, there is just one buffer. Based upon the verification result, a mask is applied to the buffer before it is written to the output buffer.

09e4b0ec9b don't reveal plaintext if authentication failed 
Create two buffers of the same size as the input data.
Copy the input data to the first one and work with that version to hold the
decrypted data, zeroize the second one.
Copy depending on the verification result, either the zero-buffer or the
real plaintext to the output buffer.

Sebastian Verschoor
25af184cd5 Quickfix for issue #73 
The API of the function is changed (for decryption, tag is now an input
parameter). With the old API it is impossible to confirm to the NIST
specification and a timing sidechannel leak is inevitable.

in the same way XMEMCMP, XMEMCPY,... are.
