From: Wang Xiaoguang <wangxg.fnst@cn.fujitsu.com>

Introduce type based metadata reserve parameter for delalloc space
reservation/freeing function.

The problem we are going to solve is, btrfs use different max extent
size for different mount options.

For compression, the max extent size is 128K, while for non-compress write
it's 128M.
And furthermore, split/merge extent hook highly depends that max extent
size.

Such situation contributes to quite a lot of false ENOSPC.

So this patch introduces the facility to help solve these false ENOSPC
related to different max extent size.

Currently, only normal 128M extent size is supported. More types will
follow soon.
