Fix Disabled property in Smbios/Block config. Move flagstate in GlobalConfig. Remove gSettings.Smbios.REV, ECPI, RBr and RPlt. Create getRBr() and getRPlt(). Operator == and isEqual in XArray, XObjArray, SETTINGS_DATA. Rename equal to isEqual in XString and XStringArray. Operator == in INPUT_ITEM, undefinable, ABSTRACT_PATCH (and derived) and RAM_SLOT_INFO class. Clean b64cdecode.h.

* 0: GUID_partition_scheme *240.1 GB disk0

* 2: Apple_APFS Container disk1 239.2 GB disk0s2
|
|
* 3: Apple_KernelCoreDump 655.4 MB disk0s3
|
|
*
|
|
* /dev/disk1 (synthesized):
|
|
* #: TYPE NAME SIZE IDENTIFIER
|
|
* 0: APFS Container Scheme - +239.2 GB disk1
|
|
* Physical Store disk0s2
|
|
* 1: APFS Volume Macintosh SSD 170.8 GB disk1s1
