Convert build process to autotools
Replaced the use of a manual Makefile with the use of autotools to
automatically verify and generate the necessary build files. Follow the
steps outlined within the README.md file to build the package.

+// For the First partial add eSEL the SEL Record ID and offset
+// value should be 0x0000. The extended data needs to be in
+// the form of an IPMI SEL Event Record, with Event sensor type
+// of 0xDF and Event Message format of 0x04. The returned
+// Record ID should be used for all partial eSEL adds.
+//
+// This function creates a /tmp/esel file to store the
+// incoming partial esel. It is the role of some other
+// function to commit the error log in to long term
+// storage. Likely via the ipmi add_sel command.
