Only odd addresses may be programmed to the ERXRDPT registers, so
initialize them to RX_BUF_END instead of RX_BUF_START.

The Bit Field Set and Bit Field Clear commands are more efficient than
the Read Control Register + Write Control Register combination, so use
them whenever possible, i.e. for the ETH registers.

This only applies to half duplex, so the actual configuration of MACON4
does not need to be changed.

The register 0x01 in bank 2, named MACON2 in the code, is actually
reserved, so its contents must not be changed.
This register has been marked as reserved from the revision B of the
data sheet in July 2006. The current revision of the data sheet is E,
and it is quite clear about this register.

This is useful as debug information since the revisions of this device
have notable differences.

A delay of 1 ms must be added after the System Reset Command. Still wait
for ESTAT.CLKRDY afterwards as a precaution.

The Read Control Register command requires that a dummy byte be read
before the register value for the MAC and MII registers.

The read/writedatabyte() functions are just a special case of
read/writedata() with a simpler API, so reuse these instead of
duplicating code.

There are scenarios in which it is beneficial to search for an Etherne chip at several i/o locations. To do so the chip initialization is performed at several i/o locations until it succeeds. In order to allow for that operation model the i/o location fixup needs to be repeatable.
Note: This won't work with the RR-Net because the fixup bits overlap with the chip i/o bits.
Enabling this option seems to greatly improve transciever performance with
Contikimac. This seems to happen because Contikimac CCAs are much less likely
to detect false positives (thus screwing up the CCA sequence).
The default Telnetd idle timeout of 30 seconds seems somewhat short. Best to have it user-configurable (incl. the option to turn it off with an config value of 0).
The .2mg image format contains a header which is missing from our file. So our file is rather a .po image.
I opted to not add the .2mg header as it is only necessary if the metadata it contains differs from the values "guessed" when using the "naked" .po image format. On the other hand there are image file consumers not understanding the .2mg image format.
In order to have the wget command make some sense the write command should be present too.
- On the Apple][ reduction of the MTU seems to gain just enough RAM to have the (rather heavy-weight) full-blown C library file I/O working.
- On the C128 there's way too little RAM so there's no wget command but only the file commands.
- On the CBMs a dummy lseek() was necessary to have the read command link.
Parts of the stm32w108 doxygen comments have explicit links to symbols that do not exist anywhere in our source base, let alone be documented. This is likely to be caused by a partial import of manufacturer libraries in the Contiki source tree.
These links were previously not generating warnings in the doxygen log because we were not defining `DOXYGEN_SHOULD_SKIP_THIS` and they were thus being skipped altogether by the doxygen pre-processor. Defining `DOXYGEN_SHOULD_SKIP_THIS` causes those doxygen comments to get processed and to thus generate warnings.
This commit removes explicit links to non-existent symbols and updates `doxyerrors.cnt` accordingly.
