to reflect the new license.
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.

Implement the interceptors for popen(), pclose() and popenve()
functions. The first two are POSIX, the third one is specific
to NetBSD. popen() spawns a process and creates a FILE object piping
data from/to that process. pclose() closes the pipe and waits for
the process to terminate appropriately.
For the purpose of popen(), the COMMON_INTERCEPTOR_FILE_OPEN macro is
modified to allow null path parameter.

Update the interceptor for devname_r() to account for correct return
types on different platforms. This function returns int on NetBSD
but char* on FreeBSD/OSX. Noticed by @krytarowski.

- Disabled on purpose on Android and Darwin platform (for now).
- Darwin supports it, would need interception in its specific code before enabling it.
- Linux does not support it but only via third party library.
- Android supports it via bionic however it is known to have issue with older versions of the implementations. Can be enabled by an Android committer later on if necessary once there is more 'certainity'/been more tested.

Fix the sha2 interceptor macros to use a constant for array parameter
length rather than referencing the extern variable. Since the digest
length is provided in hash name, reuse the macro parameter for it.
Verify that the calculated value matches the one provided by system
headers.

Summary:
This fixes the `ThreadSanitizer-x86_64-iossim` testsuite which broke
when r348770 (https://reviews.llvm.org/D55473) landed.
The root cause of the problem is that early-on during the iOS simulator
init process a call to `sysctlbyname` is issued. If the TSan initializer
is triggered at this point it will eventually trigger a call to
`__cxa_at_exit(...)`. This call then aborts because the library
implementing this function is not yet had its initialization function
called.
