tcpip_adapter_dhcpc_get_status() returns the actual internal value of dhcp client without any locking or TCP/IP stack context call, so when CONNECTED event fired with default settings it started DHCP client in TCP/IP stack context and at the same time mdns event handler checking actual DHCP state, which could still be INIT (not STARTED). Purpose of this check is to enable PCB if DHCP was stopped before setting network interface up (typically static IP settings), so the solutin is to check against TCPIP_ADAPTER_DHCP_STOPPED state

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 fixes the issue that if Wi-Fi is stopped from a shutdown handler,
the code in connect.c tries to reconnect, and fails because Wi-Fi is
already stopped.
Also make the error check in connect.c less strict.

In case of invalid name entry, only this entry is invalidated and parsing continues as other query entries could contain questions to be responded to

Issue: MDNS server initially sends probing packets to resolve naming confilicts with already registered service instances. In case of a conflict, instance name is altered and probing restarts. Original instance however wasnnot removed from the structure and upon service removal only one entry was removed and a dangling service might have been kept in the structure to bring about a crash.
Resolution: Keep only one instance of a service in the probing structure.
Closes IDF-498

possible race condition: user task runs mdns_init, which enables pcbs while mdns-task already created could execute enable/disable of the same pcbs if an appropriate system event received

mnds_free() initiates stop and delete timer tasks, which after locking the mutex could lead to a dead lock in case timer task executed before deleting the task, as it would wait indefinitelly for unlocking the mutex. This condition is fixed by calling _mdns_stop_timer without locking the mutex, because there's no need to protect any data when stopping and deleting the timer task
