[runtimes][NFC] Remove filenames at the top of the license notice We've stopped doing it in libc++ for a while now because these names would end up rotting as we move things around and copy/paste stuff. This cleans up all the existing files so as to stop the spreading as people copy-paste headers around.

//
Update more file headers across all of the LLVM projects in the monorepo to reflect the new license. These used slightly different spellings that defeated my regular expressions. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351648

[libc++][C++03] Use `__cxx03/` headers in C++03 mode (#109002) This patch implements the forwarding to frozen C++03 headers as discussed in https://discourse.llvm.org/t/rfc-freezing-c-03-headers-in-libc. In the RFC, we initially proposed selecting the right headers from the Clang driver, however consensus seemed to steer towards handling this in the library itself. This patch implements that direction. At a high level, the changes basically amount to making each public header look like this: ``` // inside <vector> #ifdef _LIBCPP_CXX03_LANG # include <__cxx03/vector> #else // normal <vector> content #endif ``` In most cases, public headers are simple umbrella headers so there isn't much code in the #else branch. In other cases, the #else branch contains the actual implementation of the header.

[libc++] Add #if 0 block to all the top-level headers (#119234) Including The frozen C++03 headers results in a lot of formatting changes in the main headers, so this splits these changes into a separate commit instead. This is part of https://discourse.llvm.org/t/rfc-freezing-c-03-headers-in-libc.

[libc++] Add missing __has_include checks for C headers not provided by libc++ This makes the library consistent in how it handles C library headers. For C headers provided by libc++, we unconditionally include <foo.h> from <cfoo>, and then <foo.h> conditionally include_next <foo.h>. For headers not provided by libc++, <cfoo> conditionally includes the system's <foo.h> directly. Differential Revision: https://reviews.llvm.org/D138512
