extension of the (small) Serial File System pC/SFS

The pC/SFS (small) Serial File System was getting an optional extension SFS_RemoveDirTree(..). The link-handling was also corrected.
A directory can now be deleted completely with all contained sub-elements (Dir / File / Link). However, a link from outside into this sub-tree can not be resolved and thus remains as an error. All other links (internal or external) may be resolved.

correction in the (small) Serial File System pC/SFS

The pC/SFS (small) Serial File System was getting a correction in internal functions SFSMem_Alloc() & SFSCreate_Entry().
The creation of a directory wasn't working cleanly.

new port of the RTOS kernel pC/OS

		The pC/OS Kernel was ported to the Synopsys ARC-EM. The nSIM simulation and the ARC-EMSK FPGA-board were used for this. This ARC-EM port does also not include active support for the TEE (here SecureShield) like the ARMv8M port, so all functions in the secure-side are to be treated as a collection of a single resource, so only one task can be in the secure-side (SecureShield) using a function call. Also, the pC/SFS (small) Serial File System has been ported to the Synopsys ARC-EMSK board.

tiny correction in the (small) Serial File System pC/SFS

The pC/SFS (small) Serial File System was getting a small correction in internal function SFSChange_Entry().
The API-function call SFS_ChangeDir("/") wasn't working correctly.
