Make MatchFun a template parameter in TemplateHashMapImpl, moving the
PointersMatch function down to an implementation which extends
TemplateHashMapImpl to void* key and value (i.e. the same as the current
HashMap and ZoneHashMap typedefs).
This will allow other instantiations of TemplateHashMapImpl, with
different MatchFun values, e.g. std::equal_to, to have their key
equality test inlined, rather than calling a function pointer,

We ported hashmap.h into libsampler as a workaround before, so the main focus of
this patch is to reduce code duplication. This patch moves the hashmap into
src/base as well as creates DefaultAllocationPolicy using malloc and free.

Currently attached references are only used for global proxy, source
string and code stubs. Mid-term future we want to use attached
references for arbitrary objects (in fixed order) provided from outside.
This change renames BackReference to SerializerReference to include both
back references and attached references.
