src/include/assert.h, branch upstream/11.2.0

Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code. Revert with prejudice. This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes. Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes. Requested by: gjb (re)

Partial merge of the SPDX changes

These changes are incomplete but are making it difficult to determine what other changes can/should be merged. No objections from: pfg

Don't define static_assert for C++.

Even though _Static_assert() is pretty robust for C code, it cannot work correctly with C++ code. This is due to the fact that C++ template parameters may contain commas that are not enclosed in parentheses. For example: static_assert(foo::bar == baz, "..."); This causes _Static_assert to be called with an excessive number of parameters. If you want to use static_assert in C++, just use a C++11 compiler. Reported on: current@, ports@

As per C11, add static_assert() to .

Add missing dead2 to assert().

__assert() is called when an assertion fails. After printing an error message, it will call abort(). abort() never returns, hence it has the __dead2 attribute. Also add this attribute to __assert(). MFC after: 3 weeks

Remove the Berkeley clause 3's.

Add a few $FreeBSD$

Only protect the prototypes with #ifndef _ASSERT_H_, the standards

2007-12-01T19:28:13Z

specifically allow changes to the NDEBUG macro between #includes of assert.h

Add missing #ifndef _ASSERT_H_ protection against multiple inclusions

Breath deep and take __P out of the system include files.

# This appears to not break X11, but I'm having problems compiling the # glide part of the server with or without this patch, so I can't tell # for sure.

Restore K&R prototype. Fix other style bugs.
