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)

The same is also done in . Submitted by: Andrzej Tobola Reviewed by: davidxu Approved by: philip (mentor, implicit)

can be used as replacements for exec/fork in a lot of cases. This change also added execvpe() which allows environment variable PATH to be used for searching executable file, it is used for implementing posix_spawnp(). PR: standards/122051
