We need to make sure that if we migrate a thread to another
memory domain, the migration process doesn't cause the target
thread to explode. This is mostly a concern on SMP systems;
the thread could be running on another CPU at the same time.

- z_x86_userspace_enter() for both 32-bit and 64-bit now
call into C code to clear the stack buffer and set the
US bits in the page tables for the memory range.
- Page tables are now associated with memory domains,
instead of having separate page tables per thread.
A spinlock protects write access to these page tables,
and read/write access to the list of active page
tables.
- arch_mem_domain_init() implemented, allocating and
copying page tables from the boot page tables.
- struct arch_mem_domain defined for x86. It has
a page table link and also a list node for iterating
over them.

Page table management for x86 is being revised such that there
will not in many cases be a pristine, master set of page tables.
Instead, when mapping memory, use unused PTE bits to store the
original RW, US, and XD settings when the mapping was made.
This will allow memory domains to alter page tables while still
being able to restore the original mapping permissions.

Call mbedtls_ssl_conf_max_frag_len() on created TLS context
configuration, so that Maximum Fragment Length (MFL) will be sent to
peer using RFC 6066 max_fragment_length extension. MFL value is
automatically chosen based on MBEDTLS_SSL_OUT_CONTENT_LEN and
MBEDTLS_SSL_IN_CONTENT_LEN mbed TLS macros.
This extension is mostly useful for TLS client side to tell TLS server
what is the maximum supported receive record length.

This pointer is 4 byte aligned. On x86 and x86_64 struct _thread_arch

If the peer ACKs data when it closes the connection, update

Signed-off-by: Jukka Rissanen <jukka.rissanen@linux.intel.com>
When a connection is being closed, it is possible that the application
will have a lock to net_context and TCP2 connection lock. If we then
receive a final TCP2 ACK and close the connection, the locking order
get switched and TCP2 will first try to get its own lock and then the
net_context lock. This will lead to deadlock as the locking ordering
is now mixed.
The solution is to unref the TCP connection after releasing the
connection lock. The TCP connection unref function will anyway get the
lock so no need to do double locking.

Introduce TagoIO IoT Cloud HTTP post client example. This explorer
Zephyr network resources to demonstrate an end to end application.
The TagoIO allows that any user can test on a easy way Ethernet, WIFI
and Modem (PPP) with BSD sockets. The example provides overlays to
configure WIFI and Modem.
The application consists an a pseudo temperature sensor that sends
periodically data to TagoIO IoT Cloud platform. The data can be
visualized on a web browser dashboard, cellphone or tablet. The
steps to configure TagoIO are described on the example documentation.
Special Variables:
- CONFIG_TAGOIO_DEVICE_TOKEN DEVID token generated by TagoIO
- CONFIG_TAGOIO_HTTP_WIFI_SSID SSID when using WIFI
- CONFIG_TAGOIO_HTTP_WIFI_PSK PASSWD when using WIFI
- CONFIG_MODEM_GSM_UART_NAME UART label when using MODEM
- CONFIG_MODEM_GSM_APN APN when using MODEM

So far there was 100ms timeout on allocation of RX net_pkt. This is too
little for cases when lots of data are incoming on pretty
fast (e.g. 1Mbps) UART interface and application layer does not consume
received network packets fast enough. Up to now in such cases all
incoming data was processed from UART and there was no data loss when
utilizing hardware flow control. However there was high chance that data
processed from UART could not be passed further to network stack,
because of the 100ms net_pkt allocation timeout. This happens for
example when low priority application does not have enough time to run.
Increase default RX net_pkt allocation timeout from 100ms to 5s, so
there is much more time to process network packets. Such timeout should
not harm, because only a dedicated RX thread will be suspended for that
time, resulting in suspending UART traffic if hardware flow control is
supported.

Its child_binding instance attribute has a compatible which can be
