block: replace REQ_NOIDLE with REQ_IDLE
Noidle should be the default for writes as seen by all the compounds definitions in fs.h using it. In fact only direct I/O really should be using NODILE, so turn the whole flag around to get the defaults right, which will make our life much easier especially onces the WRITE_* defines go away.
This assumes all the existing "raw" users of REQ_SYNC for writes want noidle behavior, which seems to be spot on from a quick audit.

block: get rid of bio_rw and READA
These two are confusing leftover of the old world order, combining values of the REQ_OP_ and REQ_ namespaces. For callers that don't special case we mostly just replace bi_rw with bio_data_dir or op_is_write, except for the few cases where a switch over the REQ_OP_ values makes more sense. Any check for READA is replaced with an explicit check for REQ_RAHEAD. Also remove the READA alias for REQ_RAHEAD.

f2fs: support revoking atomic written pages
f2fs support atomic write with following semantics: 1. open db file 2. ioctl start atomic write 3. (write db file) * n 4. ioctl commit atomic write 5. close db file
With this flow we can avoid file becoming corrupted when abnormal power cut, because we hold data of transaction in referenced pages linked in inmem_pages list of inode, but without setting them dirty, so these data won't be persisted unless we commit them in step 4.
But we should still hold journal db file in memory by using volatile write, because our semantics of 'atomic write support' is incomplete, in step 4, we could fail to submit all dirty data of transaction, once partial dirty data was committed in storage, then after a checkpoint & abnormal power-cut, db file will be corrupted forever.
So this patch tries to improve atomic write flow by adding a revoking flow, once inner error occurs in committing, this gives another chance to try to revoke these partial submitted data of current transaction, it makes committing operation more like aotmical one.
If we're not lucky, once revoking operation was failed, EAGAIN will be reported to user for suggesting doing the recovery with held journal file, or retrying current transaction again.

This patch adds FASTBOOT flag into checkpoint as follows.
- CP_UMOUNT_FLAG is set when system is umounted. - CP_FASTBOOT_FLAG is set when intermediate checkpoint having node summaries was done.
So, if you get CP_UMOUNT_FLAG from checkpoint, the system was umounted cleanly. Instead, if there was sudden-power-off, you can get CP_FASTBOOT_FLAG or nothing.

f2fs: merge flags in struct f2fs_sb_info
Currently, there are several variables with Boolean type as below:
struct f2fs_sb_info { ... int s_dirty; bool need_fsck; bool s_closing; ... bool por_doing; ... }
For this there are some issues: 1. there are some space of f2fs_sb_info is wasted due to aligning after Boolean type variables by compiler. 2. if we continuously add new flag into f2fs_sb_info, structure will be messed up.
So in this patch, we try to: 1. switch s_dirty to Boolean type variable since it has two status 0/1. 2. merge s_dirty/need_fsck/s_closing/por_doing variables into s_flag. 3. introduce an enum type which can indicate different states of sbi. 4. use new introduced universal interfaces is_sbi_flag_set/{set,clear}_sbi_flag to operate flags for sbi.
After that, above issues will be fixed.
