common-licenses: Additions and corrections

I've added more licenses from SPDX and corrected the gcc license
so that it is a. parsable and b. accurate to the SPDX standard.

I've also done some cleanup of license text and gdb's LICENSE
field.

+ANTLR SOFTWARE RIGHTS
+
+ANTLR 1989-2006 Developed by Terence Parr
+Partially supported by University of San Francisco & jGuru.com
+
+We reserve no legal rights to the ANTLR--it is fully in the
+public domain. An individual or company may do whatever
+they wish with source code distributed with ANTLR or the
+code generated by ANTLR, including the incorporation of
+ANTLR, or its output, into commerical software.
+
+We encourage users to develop software with ANTLR. However,
+we do ask that credit is given to us for developing
+ANTLR. By "credit", we mean that if you use ANTLR or
+incorporate any source code into one of your programs
+(commercial product, research project, or otherwise) that
+you acknowledge this fact somewhere in the documentation,
+research report, etc... If you like ANTLR and have
+developed a nice tool with the output, please mention that
+you developed it using ANTLR. In addition, we ask that the
+headers remain intact in our source code. As long as these
+guidelines are kept, we expect to continue enhancing this
+system and expect to make other tools available as they are
+completed.
