common: rename UNIQUE_VAR to UNIQUE_NAME, and move it to its own header
I'd like to use UNIQUE_VAR() outside of "common/utils/cleanup.h"; also,
I'd like to use it for type names as well.
Give UNIQUE_VAR() its own header file, and rename it to UNIQUE_NAME().
A number of Makefiles (using the cleanup module) have to be refreshed;
while at it, make sure the "-I$(top_srcdir)/..." lists are consistently
sorted, and terminated with $(NULL).
