a7e82666bc misc/printk: Add a function to get the current hook function.
This can be necessary at run-time if a switch of one console to
another has to be made, with the possibility to reinstall the former
hook at some point.

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

244a4dfe73 printk: Export _vprintk similar to how _prf is exported
There are some corner cases where direct access to the formatter
function is needed. Export _vprintk() so code can use it in a similar
way that _prf() can be directly used.

3ab60466de printk: Refactor to allow passing a parsing context around
Pass a parsing context around, allowing counting the number of
characters written, which is then returned in the return value of
printk(). This makes printk more similar to printf and prepares the
way to extend the implementation to support printing to strings.

bde20d5447 printk: Add basic support for width modifier and zero padding
This adds basic support for width modifier when printing integers.
Supported specifiers are u,i,d,x,X. Width '*' is not supported.
Flag '0' for left-pading number with zero is also supported.

examples:
printk("0x%x 0x%02x 0x%04x 0x%08x\n", 1, 1, 1, 1);
0x1 0x01 0x0001 0x00000001

printk("0x%x 0x%2x 0x%4x 0x%8x\n", 1, 1, 1, 1);
0x1 0x 1 0x   1 0x       1

This should make printk usable for pretty printing u8 and u16 integers.

a811cc5085 printk: make _char_out globally accessible
This is to support a printf test case where we need to know
the existing value so we can chain it.

907a99933a printk: "support" some modifier codes
We now allow modifier codes h, l, and z, although at the
moment they are simply dropped. This is to allow us to warn on
incorrect printk() usage by the compiler. These arguments get
promoted to int when they are passed as arguments so this
may never need to be addressed, although there may be implications
for (future) support for systems with 16-bit integers.
We still don't print 64-bit integers properly. but this is
nothing new.

af7d3fb116 misc: remove old printk() stub
It was never being used due to the obj-$(CONFIG_PRINTK) in the
Makefile, and the new method using a static inline function in
the printk.h header performs better since there won't be
function call overhead.
