autoconf: refactor ostype.m4
Further refactoring of the autoconf macros. Move more linux and solaris
specific checks into their own files.
This is a non-functional change. Care has been taken preserve the
ordering of the autoconf tests. Except for whitespace, the generated
configure file has not been changed by this refactoring. This has been
verified with a 'diff -u -w -B' comparison of the generated configure
file before and after applying this commit.
