Improve decoding of Android's PR_SET_VMA prctl
Before:
prctl(0x53564d41 /* PR_??? */, 0, 0x7f8ab53000, 4096,
"atexit handlers") = 0
After:
prctl(PR_SET_VMA, PR_SET_VMA_ANON_NAME, 0x7fa8cbd000, 4096,
"atexit handlers") = 0
* prctl.c (SYS_FUNC(prctl)) [__ANDROID__]: Do not define PR_SET_VMA.
* Hard-code PR_SET_VMA_ANON_NAME, the only current sub-option.
* xlat/prctl_options.in: Add PR_SET_VMA.

Add copyright headers to some files which lack them
Before this change, all files that exist since 20th century had
copyright headers, while most files that appeared later didn't. This
change fixes the inconsistency by adding missing copyright headers.
It doesn't mean that copyright headers became maintained. In my view,
git history provides much better information on this subject and is much
more accurate than copyright headers.

Fix printing tracee's long integers
