test.h introduces a PLANNED_TEST() macro for C code, shows what tests
are provided and so on (the nobug version did that since some time).
test names are now passed as identifers and translated to strings by the
macros.
A lot fixes for existing tests, replace some printfs with ECHO, cosmetics.
one threadpool (sync_many) test is broken and set to PLANNED, this needs
further testsuite support for dispatching output.
add a TEST nobug flag to test.h
* add frontend interfaces to file to get a mmaping
* SECTION macro to encapsulate mmap access
* mmap_address() translating an actual offset to address
* add some tests
* some test cosmetics
Quite some code which was hold back in favor of the config and plugin stuff
implements:
* mmapcache: mru cache for unused memory mappings
* mmap: single mmaped areas
* mmapings: manages mmaps established for one filedescriptor
