Fix/refactor RELOAD VLI implementation to support negative and 64bit ints; add lots of testcases.

-Encoding of negative numbers was completely broken due to a typo
 (This typo produced a compiler warning when compiling with -gen gcc!)
 However RELOAD files do not contain negative VLI numbers
-ReadVLI only supported 32 bit ints, returning wrong answer otherwise
 (except in 64 bit builds)
-I have changed the encoding of negative numbers. Now the bitwise
 complement is stored rather than the negation. This allows
 -2^63 to be encoded. No change to the RELOAD version number is necessary.
-Read/WriteVLI were duplicated for two different types of file input/output,
 so I combined them by using macros
-Testcases check that all these functions give expected results.
