LWIP has two definess for setting max number of sntp servers:
- Total number of handled servers
- max number of sntp's picked via DHCP
by default both values are equal to 1, but could be set separately

This commit brings two esp-lwip fixes to IDF:
1) Add configuration to disable DHCP client identification
2195f7416f
This config could be used to disable option 61 in DHCP packets, so that
clients will be identified by their chaddr only.
(This is the lwip upstream original behaviour)
2) Fix server_idx increasing to DNS_MAX_SERVERS and trigger the LWIP_ASSERT
5a567d52f7
When lwip doesn't have DNS server and resolve a domain address, the server_idx
will increase to DNS_MAX_SERVERS, which will trigger the LWIP_ASSERT and make device crash.
Closes https://github.com/espressif/esp-idf/issues/6878
If silent assert configuration is enabled, LWIP asserts are now 'silent' also.
Also updates KConfig to note that LWIP asserts are also disabled when asserts
are disabled globally (this was already the behaviour, but the config item
suggested otherwise.)
Progress towards https://github.com/espressif/esp-idf/issues/5873
Added lwIP hooks which could be optionally overwritten in the
application code. These three options are provided in Kconfig:
* NONE: No hook support
* DEFAULT: Default implementation is provided. If IDF doesn't
have a specific hook implementation, an empty stub is provided, which
could be overwritten by strong implementation in application code.
* CUSTOM: Hooks are declared only to be implemented in application code.
Merges https://github.com/espressif/esp-idf/pull/6034
* If CONFIG_VFS_SUPPORT_IO=y, keep everything as it is now
* If CONFIG_VFS_SUPPORT_IO=n, defined syscalls which LwIP can
implement, such as read/write/close
* Make LWIP-only select implementation dependent on
CONFIG_VFS_SUPPORT_SELECT, deprecate CONFIG_LWIP_USE_ONLY_LWIP_SELECT
Make the link local negotiation for IPV6 in PPP optional and
configurable.
This is because some modems do not support the IPV6 negotiation and
sending IPV6CP frames would in some cases break the network
configuration phase, resulting in a timeout during the Phase Network.
Please note that this does not disable the IPV6 support for the outgoing
communication (IPV6 is still enabled even if this option is not
selected) but just for the local link between lwIP and modem.

On startup of the common interface (ethernet, wifi), the lwip netif hostname was assigned to confg value .
Fixed to assign to esp-netif hostname if it exists
