[BUG]
Since commit dad03fac3b ("btrfs-progs: switch btrfs_group_profile_str
to use raid table"), fstests/btrfs/023 and btrfs/151 will always fail.
The failure of btrfs/151 explains the reason pretty well:
btrfs/151 1s ... - output mismatch

[CAUSE]
Commit dad03fac3b ("btrfs-progs: switch btrfs_group_profile_str to use
raid table") will use btrfs_raid_array[index].raid_name, which is all
lower case.
[FIX]
There is no need to bring such output format change.
So here we split the btrfs_raid_attr::raid_name[] into upper_name[] and
lower_name[], and make upper and lower case helpers for callers to use.
Now there are several types of callers referring to lower_name and
upper_name:
- parse_bg_profile()
It uses strcasecmp(), either case would be fine.
- btrfs_group_profile_str()
Originally it uses upper case for all profiles except "single".
Now unified to upper case.
- sprint_profiles()
It uses lower case.
- bg_flags_to_str()
It uses upper case.

There are some duplicate parsers of the profile names, factor out the
one from balance to the common code.

There are various parsing helpers scattered everywhere, unify them to
one file and start with helpers already in utils.c.
