This commit updates all authorship and copyright information to include a
standard header that references the AUTHORS and CREDITS file. This standard
header was written by the Debian legal team at the request of Franck Joncourt.
Integer lengths that are negative are never valid. This commit also
extends the fuzzing capabilities of the test/fko-wrapper code to
validate libfko calls with negative length arguments, and one crash
scenario with a negative length for the encryption key was found (and
fixed) this way.
Added the 'const' qualifier to function prototype variables where possible.
In addition, reduced some functions to file-scope with 'static' where possible.
Also made a few minor changes to remove extra whitespace, and fixed a bug
in create_fwknoprc() to ensure the new fwknoprc filehandle is closed.
cipher_funcs.c:85: warning: ignoring return value of ‘fread’, declared with attribute warn_unused_result
A few of these were in code in the lib/ directory, and required adding a
new error code 'FKO_ERROR_FILESYSTEM_OPERATION' and associated error
string 'Read/write bytes mismatch'.
