This addresses GHSL-2020-075 as well as all other problematic code
uncovered as a result of investigating that. This includes:
- buffer overflows due to use of unchecked lengths
- integer overflows due to type conversions
- potential memory leaks
- checking for memory allocation failures
Re #279.
Source code was inconsistent on how they were referencing
include files in include/sane. In certain cases, sane/sane.h
and sane/saneopts.h was really including external copies (with
some preprocessor implementations anyways).
in multiple files, added networking
support, added FS G extended handshaking mode,
make proper use of extended commands when possible
* sanei/sanei_tcp.c: read now wait until all
the requested data is available.
