Minor fix for an uninitialized var
Place docs in @docdir@
Build a shared library by default
Minor whitespace cleanup in automake files
Slightly cleaner way to handle docdir subdirectories

This avoids overriding ${docdir} as given at the command line so it
won't be inconsistent in a few Makefiles.
Set autoconfig prereq to 2.60
Update gitignore to exclude distcheck output
Move bufoverrun test to libcheck
Add standard defines in case __UD_STANDALONE

Defines are required for uint16_t etc., size_t, and va_list in case of
__UD_STANDALONE on linux.  The stddef.h and stdarg.h defines would
otherwise come from stdio.h were it included.
