Johan Hedberg c14c2692e2 net: buf: Set default user data size to 4
Since all in-tree users are good with 4 bytes of user data, reduce the
default to 4. Also fix the default and rage values where apparently
'0' and '8' had been swapped.

Johan Hedberg 7aeb1fa136 net: buf: Remove incorrect dependency for NET_BUF_POOL_USAGE
NET_BUF_POOL_USAGE was never supposed to depend on NET_BUF_LOG.

Johan Hedberg dd09cbc1c4 net: buf: Redesigned API with split data and meta-data
Redesign of the net_buf_simple and net_buf structs, where the data
payload portion is split to a separately allocated chunk of memory. In
practice this means that buf->__buf becomes a pointer from having just
been a marker (empty array) for where the payload begins right after
the meta-data.

Fixes #3283

Paul Sokolovsky d9e886bc6e net: Kconfig: Don't select STDOUT_CONSOLE
The net code doesn't use libc stdio stdout in any way, so there's no
need tweak those options.

Leandro Pereira da9b0ddf5b drivers: Rename `random` to `entropy`
This should clear up some of the confusion with random number
generators and drivers that obtain entropy from the hardware.  Also,
many hardware number generators have limited bandwidth, so it's natural
for their output to be only used for seeding a random number generator.

Tomasz Bursztyka e38a9e8b9c net: Switch from per-iface tx thread to a unique k_poll triggered one
Now that k_poll landed in the kernel, it's worth using it to save
memory and reduce the number of threads at runtime.

Such switch has been first done in bluetooth (see hci_core.c and conn.c
in subsys/bluetooth/host). Since network interfaces kind of follows the
same design for sending data, it was then easy to copy the same change as
in bluetooth.

David B. Kinder ac74d8b652 license: Replace Apache boilerplate with SPDX tag
Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.

Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.

Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file.  Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Jira: ZEP-1457
