Integrate libexplain to provide better error explanations

[cfsmp3]

http://libexplain.sourceforge.net/

is a library that wraps a number of OS calls and on failure provide useful description of what went wrong. It seems like a good idea to integrate it, and not really a lot of work.

Libexplain will only work on Linux and Mac sadly.

Sadly there also external dependencies that will need to be installed using a packet manager which I don't think the End user would want.

The external dependencies a user would need to install is: libcap

• lsof -> tool that lists open files
• GNU libtool -> GNU libtool is a generic library support scrip
• bison -> Bison is a general-purpose parser generator that converts an annotated context-free grammar into a deterministic LR or generalized LR (GLR) parser
• GNU Groff -> typesetting system that reads plain text mixed with formatting commands and produces formatted output.
• GCC -> Standard Compiler

Which would result in a 4 additional depedencies that will only work for Linux and Mac.

Closing, definitely more work than anticipated. Not going to happen.
