Qunxin Liu 8eadb83640 [subset] Update hb_subset_input_override_name_table API
Override the name string for the NameRecord identified by name_id,
platform_id, encoding_id and language_ids specified by the user.
If a record with specified name_id does not exist, this API will create
a new NameRecord with provided info and insert it to the name table.

Garret Rieger 2c0afde737 [subset] add an inprogress accelerator to plan.
This allows subset code to cache information into the accelerator during preprocess subset. Previously the accelerator was created at the end of subsetting.

Garret Rieger 463ae07e99 [subset] In the preprocess subset call always use long loca.
Long loca is needed so that we can store the trimmed glyph bytes to allow us to safely skip trimming in the later subset.
