For stream-based protocols (TCP), adding less data than requested
("short write") is generally not a problem - the rest of data can
be sent in the next packet. So, make net_pkt_append() return length
of written data instead of just bool flag, which makes it closer
to the behavior of POSIX send()/write() calls.
There're many users of older net_pkt_append() in the codebase
however, so net_pkt_append_all() convenience function is added which
keeps returning a boolean flag. All current users were converted to
this function, except for two:
samples/net/http_server/src/ssl_utils.c
samples/net/mbedtls_sslclient/src/tcp.c
Both are related to TLS and implement mbedTLS "tx callback", which
follows POSIX short-write semantics. Both cases also had a code to
workaround previous boolean-only behavior of net_pkt_append() - after
calling it, they measured length of the actual data added (but only
in case of successful return of net_pkt_append(), so that didn't
really help). So, these 2 cases are already improved.

This adds a new event type to the kernel event logger that tracks
thread-related events: being added to the ready queue, pending a
thread, and exiting a thread.
It's the only event type that contains "subevents" and thus has a
non-void parameter in their respective _sys_k_event_logger_*()
function. Luckily, as isn't the case with other events (such as IRQs
and thread switching), these functions are called from
platform-agnostic places, so there's no need to worry about changing
the assembly guts.
This is the first patch in a series adding support for better real-time

There have been long lasting confusion between net_buf and net_nbuf.
While the first is actually a buffer, the second one is not. It's a
network buffer descriptor. More precisely it provides meta data about a
network packet, and holds the chain of buffer fragments made of net_buf.
Thus renaming net_nbuf to net_pkt and all names around it as well
(function, Kconfig option, ..).
Though net_pkt if the new name, it still inherit its logic from net_buf.

next header.
Then net_ipv6_prepare_for_send() will update RPL HBH header if it exists.
But net_rpl_update_header() is comparing HBH option and IPv6 next header,
which is wrong. Wrong comparion does not update RPL instance id and
sender rank. Peer nodes drops all the packets due to invalid instance
