    • Implement git_pool paged memory allocator · 2bc8fa02
      This adds a `git_pool` object that can do simple paged memory
      allocation with free for the entire pool at once.  Using this,
      you can replace many small allocations with large blocks that
      can then cheaply be doled out in small pieces.  This is best
      used when you plan to free the small blocks all at once - for
      example, if they represent the parsed state from a file or data
      stream that are either all kept or all discarded.
      
      There are two real patterns of usage for `git_pools`: either
      for "string" allocation, where the item size is a single byte
      and you end up just packing the allocations in together, or for
      "fixed size" allocation where you are allocating a large object
      (e.g. a `git_oid`) and you generally just allocation single
      objects that can be tightly packed.  Of course, you can use it
      for other things, but those two cases are the easiest.

    • filter: Apply filters before writing a file to the ODB · 44b1ff4c
      Initial implementation. The relevant code is in `blob.c`: the blob write
      function has been split into smaller functions.
      
      	- Directly write a file to the ODB in streaming mode
      
      	- Directly write a symlink to the ODB in direct mode
      
      	- Apply a filter, and write a file to the ODB in direct mode
      
      When trying to write a file, we first call `git_filter__load_for_file`,
      which populates a filters array with the required filters based on the
      filename.
      
      If no filters are resolved to the filename, we can write to the ODB in
      streaming mode straight from disk. Otherwise, we load the whole file in
      memory and use double-buffering to apply the filter chain. We finish
      by writing the file as a whole to the ODB.
