This is the first time we see an application running out of mmap().
We essentially allocate too many batches (+65k) and end up not being
able to mmap them, at which point we can't mmap anything anymore and
things go sideways.
This change allocates bigger batch BOs as we grow an existing command
buffer. This drastically reduces the number of BOs we need to allocate
(the benchmark that reported the issue now reaches a max of ~630 BOs,
instead of reaching 65k and failing previously).
v2: Track the total batch size of command buffers (Jason)
Just give 0 for batch_len to i915 (Jason)
v3: Fix indentation (Jason)
v4: Drop uncessary reshuffling of error labels (Jason)
v5: Remove empty lines (Marcin)
v6: Limit BO growing to chunks of 16Mb (Jason)
v7: Add assert on initial size (Jason)
v8: Add define for max size (Jason)
v9: Fixup v7 assert for non softpin platforms (Lionel)
