This patch removes the string from register component.
Removed are all instances in libs or hardcoded in apps.
Starting with this patch literal passed to register,
serves as name for the flag.
All instances of SPDK_LOG_* were replaced with just *
in lowercase.
No actual name change for flags occur in this patch.
Affected are SPDK_LOG_REGISTER_COMPONENT() and
SPDK_*LOG() macros.

Some OS(Windows and VMWARE esxi) will send SPC2 RESERVE/RELEASE
commands when formatting the filesystems, but in our previous
implementation of reservation feature, we didn't add such support,
in specification SPC3/4, they all include one section "Exceptions to
SPC-2 RESERVE and RELEASE behavior" feature for compatible support of
SCP2 RESERVE/RELEASE, so we add this support now.
Fix issue #1414.
