Do a cleanup. Also make it consistent with kernel. Use fs_info instead
of root for BTRFS_NODEPTRS_PER_BLOCK, since maybe in some situation we
do not know root, but just know fs_info.
To be consistent with kernel, change macro to inline function.

Currently transaction bugs out insided btrfs_start_transaction in case
of error, we want to lift the error handling to the callers. This patch
adds the BUG_ON anywhere it's been missing so far. This is not the best
way of course. Transforming BUG_ON to a proper error handling highly
depends on the caller and should be dealt with case by case.

So I needed to add a flag to not try to read block groups when doing
--init-extent-tree since we could hang there, but that meant adding a whole
other 0/1 type flag to open_ctree_fs_info. So instead I've converted it all
over to using a flags setting and added the flag that I needed. This has been
tested with xfstests and make test. Thanks,

Mark many functions as static, and remove any resulting dead code.

Port of commit b3b4aa7 to userspace.
parameter tree root it's not used since commit
5f39d397dfbe140a14edecd4e73c34ce23c4f9ee ("Btrfs: Create extent_buffer
interface for large blocksizes")
This gets userspace a tad closer to kernelspace by removing
this unused parameter that was all over the codebase...
