f4e3ebe1e3 linker: stat /proc/self/exe instead of executable_path 
The absolute path to an executable may no longer be valid for
example when the file is unlinked immediately after exec.
Using /proc/self/exe instead of absolute path solves this problem.

Bug: http://b/31084669
Test: Run the app from http://b/31084669 make sure executable starts
Test: by checking ps and /proc/<pid>/exe

Elliott Hughes
3c1159024c Fix execvpe ENOEXEC behavior. 
The special case for absolute paths wasn't handling ENOEXEC.

Also add more extensive tests for execvpe.

Also switch to manually doing the fork in ExecTestHelper::Run because
ASSERT_EXIT doesn't actually return, meaning we were only running the
first part of each test.

Bernhard Rosenkränzer
59ba65e086 Don't warn about DT_FLAGS_1 containing DF_1_PIE 
DF_1_PIE is set in PIE code built with gcc 6.x. The flag is purely
informational and the linker doesn't need to do anything about it,
so Bionic handles it correctly - no need to warn.

Not useful except to systems/bringup folks for testing. Trivial tests
added, and double-checked under strace to see that things look right.

x86 -- which works differently to everything else -- tested on the host.

8e547bde4b Be more restrictive about max frame size. 
exec and realpath both have PATH_MAX buffers (which is a bug in its own
right, since PATH_MAX isn't a real limit). The printf/scanf implementation
has a few large functions, and the DNS implementation is a complete 1970s
C nightmare.

We could fix it for LP32, but that's probably just more confusing and
inconvenient.

http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/sys_socket.h.html

Interestingly, recvmmsg/sendmmsg do actually return int, unlike their
recv/recvmsg/sendv/sendvmsg siblings.

The generated assembler stubs don't actually change.
