There used to be dummy phase before out phase in common command
transactions. This corrupts the data.
The code before never actually operate (clear) the QE bit, once it finds
the QE bit is set. It's hard to check whether the QE set/disable
functions work well.
This commit:
1. Cancel the dummy phase
2. Set and clear the QE bit according to chip settings, allowing tests
for QE bits. However for some chips (Winbond for example), it's not
forced to clear the QE bit if not able to.
3. Also refactor to allow chip_generic and other chips to share the same
code to read and write qe bit; let common command and read command share
configure_host_io_mode.
4. Rename read mode to io mode since maybe we will write data with quad
mode one day.
OpenCores Ethernet MAC has a relatively simple interface, and is
already supported in QEMU. This makes it a good candidate for enabling
network support when running IDF apps in QEMU, compared to the
relatively more complex task of writing a QEMU model of ESP32 EMAC.
This driver is written with QEMU in mind: it does not implement or
handle things that aren't implemented or handled in the QEMU model:
error flags, error interrupts. The transmit part of the driver also
assumes that the TX operation is done immediately when the TX
descriptor is written (which is the case with QEMU), hence waiting for
the TX operation to complete is not necessary.
For simplicity, the driver assumes that the peripheral register
occupy the same memory range as the ESP32 EMAC registers, and the
same interrupt source number is used.

This change allows RTTI to be enabled in menuconfig. For full RTTI
support, libstdc++.a in the toolchain should be built without
-fno-rtti, as it is done now.
Generally if libstdc++.a is built with RTTI, applications which do not
use RTTI (and build with -fno-rtti) could still include typeinfo
structures referenced from STL classes’ vtables. This change works
around this, by moving all typeinfo structures from libstdc++.a into
a non-loadable section, placed into a non-existent memory region
starting at address 0. This can be done because when the application
is compiled with -fno-rtti, typeinfo structures are not used at run
time. This way, typeinfo structures do not contribute to the
application binary size.
If the application is build with RTTI support, typeinfo structures are
linked into the application .rodata section as usual.
Note that this commit does not actually enable RTTI support.
The respective Kconfig option is hidden, and will be made visible when
the toolchain is updated.
ICY URIs e.g `http://uk1.internet-radio.com/proxy/vombat?mp=/;` need to
be handled differently.
For basic use case, these URIs are similar to HTTP with exception that they reply with `ICY 200` etc in place of `HTTP/1.1 200`.
In http_parser, we now also parse ICY URIs to be able to handle these similar to HTTP.

1. simplify deallocate in esp_eth_mac_new_esp32, esp_eth_mac_new_dm9051
2. remove blocking operation in os timer callback
3. check buffer size in ethernet receive function
- Minor fix to remove while loop & delay while transmitting data from
host to controller.
- Add menuconfig option to enable predefined public-private keypair for
debugging (Vol. 3, Part H, 2.3.5.6.1)
Fixed error caused by unnecessary reopening of listening socket.
Extracted packet retransmit logic to separate function.
Added robust implementation for sending data
Closes https://github.com/espressif/esp-idf/pull/3597
