Resolved possible race conditions when accessing registers in different banks.
Added Tx ready semaphore when requesting packet to transmit (ENC is slow => access to it needs to be controlled).
Added setting of CS hold time based on Data sheet.
Added option to set the ENC28J60 to Full Duplex mode.
Addressed several ENC28J60 Erratas.
Restructured ENC28J60 example folder structure so the driver could be easily linked from different projects.
Extended the README to guide users of how to properly use the ENC28J60 chip.
Extended iperf example to include ENC28J60.

Console example doesn't duplicate code in `console` component.
Linenoise has been improved: it now has a parametrized command line
length. It is now possible to paste data efficiently to the console.
Note: this can only be done if the cursor is at the end of the line.

esp_netif_init() returns standard esp_err_t error code (unlike tcpip_adapter init), so shall be checked for the return value
Also to make the initialization code more consistent.
The build system automatically determines offsets of partitions from
the partition table, so no manual changes are needed. Instead, add a
note that partition offsets may need to be updated when increasing
the bootloader size.
newlib uses significantly more stack space when printing to an
unbuffered stream. To reduce the amount of stack space required to
use the console, don’t disable buffering. linenoise should support
unbuffered stdout instead.
1. Add command for Ethernet based on console component.
2. Make cmd_system and iperf a component that can be referenced by other examples
3. Add "version" command to cmd_system.c
4. Clean up the README.md in all ethernet examples[TW#26525]
