Encourage use of RTEST(), direct Qfalse comparison, and remove references to
Qfalse == 0 in extension documentation.

rb_cData is deprecated and the characteristic alloc_func was already
removed in ruby-3.0. So this updates the recommendation accordingly.
It also adds fdbm_alloc() in order to show the allocation process
and to gives TypedData_Make_Struct() more context.
Moreover it describes fdbm_aref(), so that the relation to
rb_define_method() is shown.
And fdbm_aref() makes use of GetDBM() now, to show how this macro
might be used.
These macros should make it easier to C extensions to switch to
the Ruby 2.7 C-API *_kw functions, but still have the code work
correctly on older Ruby versions.
This will hopefully be useful for folks writing C extensions.
