netutils/libshvc: implement headers export and update shv-libs4c

Browse source 
The uLUt and libshvc declare headers intended for make export
by EXPORTED_INCLUDES mechanism implemented during 2026
Micowindows GSoC. The shv-libs4c has been updated as well
to support newer pyshv versions and that way firmware updates
when shv-nxboot-updater is used through pyshv based shvflasher.py
and related GUI.

For pyshv see https://github.com/silicon-heaven/pyshv

New commits from shv-libs4c project

  https://github.com/silicon-heaven/shv-libs4c

- shv_com_common: shv_unpack_discard and shv_unpack_skip

   required to skip additional parameters and query requests
   introduced introduced by newer silicon-heaven protocol
   and pyshv. Incorrect skipping was a bug even against
   previous protocol version but did not present itself because
   older pyshv did not send additional requests which need
   to be ignored.

- shv_file_node: small, but crucial unpack change

  Ignore any other messages than PARAM in file node's write unpack
  function. Other different states should be handled, too.

- shv_file_node: fix the CRC unpack method too

  Any other messages than PARAM are ignored.

- shv_com: add a method to close a connection only

- shv_dotdevice_node.c: close the conn with the other side when resetted

- shv_com.h: use array designators for error strings

- libshvtree: move shv_con_errno_strs to the C file to not waste space
  by copies

- shvtree/shv_clayer_posix: provide alternative socketpair notification
  support

  This allows to use shv-libs4c and related pysimCoder support
  on RTEMS system which does not provide functional pipe
  directive/system call but BSD networking supported local/UNIX
  socket pair is fully supported.
