+ added a wrapper function around __wasi_path_readlink that calls it iteratively
with doubling buffer sizes, starting with 64 bytes, until it reaches 16384
bytes, and reads the link into a rawbytestring. Use that function in all
places in the WASI rtl that need to read a symlink.

* ConvertToFdRelativePath removed from the interface part of the WASI system

dependent routines) and added to a new unit, called wasiutil

* the FNMatch private helper function moved from unit DOS to unit WasiUtil, and
changed to have rawbytestring parameters, so it can be used from SysUtils as
well.

* moved the FindFirst/FindNext/FindClose code from unit DOS to WasiUtil, using
RawByteString. This will allow to reuse the same implementation in SysUtils.
