25307d5331 net: net_pkt_append: Refactor to return length of data actually added
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.

db11fcd174 net/net_pkt: Fully separate struct net_pkt from struct net_buf
- net_pkt becomes a stand-alone structure with network packet meta
  information.
- network packet data is still managed through net_buf, mostly named
  'frag'.
- net_pkt memory management is done through k_mem_slab
- function got introduced or relevantly renamed to target eithe net_pkt
  or net_buf fragments.
- net_buf's sent_list ends up in net_pkt now, and thus helps to save
  memory when TCP is enabled.

bf964cdd4c net: Renaming net nbuf API to net pkt API
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.
'
This patch is the first of a serie that will separate completely net_pkt
from net_buf.

081246737c net/http: let HTTP_SERVER, HTTP_CLIENT and HTTP_PARSER select HTTP
Due to commit 8308b9bd2d ("net/http: Add the HTTP/1.1 API")
every user of CONFIG_HTTP_PARSER would need to add CONFIG_HTTP to
their .conf files.  Which is fine for intree samples/tests as they
have been adjusted, but the rest of world working on Zephyr apps
will need to make this changes as well.

Instead, we should have each of the following select HTTP instead of
depend on it, which will make future use of these configs and their
dependencies more intuitive:
HTTP_SERVER
HTTP_CLIENT
HTTP_PARSER

NOTE: As cleanup, this commit also removes the CONFIG_HTTP added to
samples and test .conf files.

8308b9bd2d net/http: Add the HTTP/1.1 API
This patch adds the HTTP/1.1 API for Zephyr. This API consists of client
and server context structures enabled via Kconfig variables.
HTTP parser support is enabled via the CONFIG_HTTP_PARSER configuration
variable.

Currently, this API only includes support for writing HTTP requests
(client mode) and HTTP responses (server mode). TLS support is not
considered in this iteration.

Supported HTTP methods:
	GET, HEAD, OPTIONS and POST.

Supported HTTP responses:
	400, 403 404. The http_response routine may be used to write
	any HTTP status code, for example 200 OK.

d32503f57e net: nbuf: Split one global DATA pool to RX and TX DATA pools
If we receive lot of packets, it might happen that we exhaust
all the DATA buffers in the system. This would prevent from
us sending anything to the network.
Change this by splitting the DATA buffer pool into RX and TX
parts. This way RX flooding cannot consume all DATA buffers
that needs to be sent.

bd3908b2a9 net: nbuf: Add timeout to net_buf getters
This commit changes the net_buf getter functions in nbuf.h
by adding a timeout parameter. These function prototypes
are changed to accept a timeout parameter.
	net_nbuf_get_rx()
	net_nbuf_get_tx()
	net_nbuf_get_data()
	net_nbuf_get_reserve_rx()
	net_nbuf_get_reserve_tx()
	net_nbuf_get_reserve_data()
	net_nbuf_copy()
	net_nbuf_copy_all()
	net_nbuf_push()
	net_nbuf_append()
	net_nbuf_write()
	net_nbuf_insert()

Following convinience functions have not been changed
	net_nbuf_append_u8
	net_nbuf_append_be16
	net_nbuf_append_be32
	net_nbuf_insert_u8
	net_nbuf_insert_be16
	net_nbuf_insert_be32
	net_nbuf_write_u8
	net_nbuf_write_be16
	net_nbuf_write_be32
so they call the base function using K_FOREVER. Use the
base function if you want to have a timeout when net_buf
is allocated.
