[PATCH 00/18] Migration compression cleanup

[Juan Quintela]

Hi

On this series:

- We got errors when setting incompatible migration methods
  (i.e. compression and RDMA)

- Remove the posibility of running COMPRESSION and XBZRLE together
  (remember that compression don't work)

- This series is the preliminar work to be able to compile out
  compression (almost there, but wanted to get this first)

- Move everyting that touches compression_counters to ram-compress.c

- simplify pass of block/file parameter.  We can get them trough the
  pss.

Please, review.

  migration: Give one error if trying to set MULTIFD and XBZRLE
  migration: Give one error if trying to set COMPRESSION and XBZRLE
  migration: RDMA is not compatible with anything else
  migration: Remove save_page_use_compression()
  migration: Move compression_counters cleanup ram-compress.c
  migration: Create populate_compress()
  migration: Create ram_compressed_pages()
  migration: Move update_compress_threads_counts() to ram-compress.c
  migration: Make compress_data_with_multithreads return bool
  migration: Simplify compress_page_with_multithread()
  migration: Move busy++ to migrate_with_multithread
  migration: Create compression_update_rates()
  migration: Simplify decompress_data_with_multi_threads()
  migration: Use "i" as an for index in ram-compress.c
  migration: save_compress_page() can take block through pss
  migration: control_save_page() can take block through pss
  migration: Remove not needed block parameter for save_zero_page*
  migration: Remove not needed file parameter for save_zero_page*
