SWIM transport only supports two adapter speeds:
- "low speed" equal to 363 kHz (8 MHz / 22)
- "high speed" equal to 800 kHz (8 MHz / 10)
Replace the previous convention that use "0" or "1" for "low" or
"high" speed with the effective speed in kHz.
Rework the implementation of stlink_speed_swim().
Set low speed in the stm8 config files, because only low speed is
permitted at debug connection; the previous code ignores the
initial value.

SWIM is implemented by (ab)using the HLA API. This was acceptable
when OpenOCD code did not provided a clear separation between
transports and related APIs. Still today SWIM in OpenOCD is only
supported by STLink, so the decision to re-use the HLA API was the
simpler way to implement it.
After commit efd1d64222 ("adapter: switch from struct
jtag_interface to adapter_driver") the transports API are better
split and SWIM can be implemented as a separate set of API. This
would open the possibility to extend OpenOCD for other adapters
that provide SWIM, e.g. versaloon, or through SPI emulation [1].
Introduce a new set of files swim.[ch] to handle the SWIM API.
Beside the API that almost match the transport low-level data
communication (system_reset, read_mem, write_mem), add a further
API reconnect. Today, inside HLA STLink code, the reconnect is
implemented by hacking the HLA API state(). Please notice that
due to this hack the return type is incorrect; stlink_usb_state()
returns ERROR_OK in SWIM mode, while its return type is enum
target_state. Ignore the type mismatch and still call the HLA API
state in the new SWIM API reconnect. Further commit will fix it.

In the driver's code it's widely used the enum hl_transports for
any check concerning the current transport, even for the non-hla
transport dapdirect.
The driver already provides a stlink specific enum stlink_mode
that can be used in place of the hla one.
Replace the hla enum with the stlink one allover the code.
Introduce a hla specific wrapper stlink_usb_hl_open() to cope with
the only API that requires the hla specific enum.
The overall behaviour is not changed, with exception for a debug
message in stlink_usb_open() than now prints the numeric value of
stlink enum in place of the numeric value of the corresponding hla
one.
This change prepares the road for moving SWIM transport out of hla
by removing any reference to the macro HL_TRANSPORT_SWIM from the
stlink driver.

Starting from version 8, gcc issues a warning if strncpy could be
able to truncate a string (so without adding the zero-termination
char in destination) by copying exactly "size" char from a source
string not shorter than "size".
Such truncation from strncpy could actually be the desired code
behaviour, but the way to silent gcc only locally (without global
disabling with -Wno-stringop-truncation) through pragma has other
side effects on portability.
In current code, the source string is always "eth0", because has
been checked right above. So this is a false positive from gcc,
being always strlen("eth0") < 16, the sizeof(ifreq.ifr_name).
Silent gcc by decrementing the "size" and remove:
error: ‘strncpy’ specified bound 16 equals destination
size [-Werror=stringop-truncation]
This file is only optionally compiled together with ZY1000 driver
with --enable-zy1000 --enable-ioutil. This combination is not
checked in jenkins, so the error passed unnoticed.
Plus, the configure flags above are both deprecated!
