drgn is currently licensed as GPLv3+. Part of the long term vision for
drgn is that other projects can use it as a library providing
programmatic interfaces for debugger functionality. A more permissive
license is better suited to this goal. We decided on LGPLv2.1+ as a good
balance between software freedom and permissiveness.
All contributors not employed by Meta were contacted via email and
consented to the license change. The only exception was the author of
commit c4fbf7e589 ("libdrgn: fix for compilation error"), who did not
respond. That commit reverted a single line of code to one originally
written by me in commit 640b1c011d ("libdrgn: embed DWARF index in
DWARF info cache").

The syscall table will be useful outside of the test cases themselves.
Additionally, definining it in terms of the "normalized" machine name is
a little easier. The normalized machine name will be useful elsewhere,
too.

The next commit will some more syscall numbers that we need, so let's
settle on one place where we define syscall numbers.
