When the cache's memory context was in over memory state when the
cache was flushed it resulted in LRU cleaning removing newly entered
data in the new cache straight away until the old cache had been
destroyed enough to take it out of over memory state. When flushing
the cache create a new memory context for the new db to prevent this.

Because we don't use jemalloc functions directly, but only via the
libisc library, the dynamic linker might pull the jemalloc library
too late when memory has been already allocated via standard libc
allocator.
Add a workaround round isc_mem_create() that makes the dynamic linker
to pull jemalloc earlier than libc.

DSCP has not been fully working since the network manager was
introduced in 9.16, and has been completely broken since 9.18.
This seems to have caused very few difficulties for anyone,
so we have now marked it as obsolete and removed the
implementation.
To ensure that old config files don't fail, the code to parse
dscp key-value pairs is still present, but a warning is logged
that the feature is obsolete and should not be used. Nothing is
done with configured values, and there is no longer any
range checking.

The libtest.la headers were installed in very weird place, in fact, we
don't need to list them in the HEADERS variable, listing them in SOURCES
is enough for autotools to figure out how to compile the convenience
library.

Move the libtest code into a 'libtest' subdirectory and make it
one of the SUBDIRS in the tests Makefile. having it at the top level
required having "." as one of the subdirs, and that caused the
unit tests to be executed twice.
