fdr: move long literal handling into Rose

Browse Source 
Move the hash table used for long literal support in streaming mode from
FDR to Rose, and introduce new instructions CHECK_LONG_LIT and
CHECK_LONG_LIT_NOCASE for doing literal confirm for long literals.

This simplifies FDR confirm, and guarantees that HWLM matchers will only
be used for literals < 256 bytes long.
