Michael Hope ce3b2edef3 libc: add EILSEQ for use in reporting checksum failure.
This code is commonly used in the Linux kernel for reporting a
retryable error like a failed CRC.  This name and value is already
present in Linux and newlib.

Paul Sokolovsky 8cc6f6ddd6 kernel: errno: Use per-thread accessor function compatible with Newlib
Newlib names this function __errno(), so if we want Zephyr to work
with Newlib seamlessly, it's better to just follow Newlib's naming
convention for Zephyr's own minimal libc.

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.

Anas Nashif c83e6a1f48 libc: define EWOULDBLOCK to be the same as EAGAIN
EWOULDBLOCK is an old error code from BSD. Not much uses it, and on basically
all modern systems it's defined to the same value as EAGAIN, which is the
System V value for the same condition.

Benjamin Walsh fc1c0c3345 libc/minimal: use per-thread errno implementation
Provides proper access to the per-thread errno variable, by using the
_get_errno() call.

Users can now do:

  errno = EINVAL;
  printk("errno: %d\n", errno);
