Allow the setting of the maximum key length, this allows the testing of
index key truncation code. Index key truncation is required to allow
the samba indexing scheme to be used with backends that enforce a
maximum key length.
This will allow emulation of a length-limited key DB for testing.
This is a testing-only feature, as the index format changes
based on this value.
