87b7292aa5 Relicense drgn from GPLv3+ to LGPLv2.1+
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").

1fe01bb4b8 libdrgn: python: add call_tp_alloc()
There are a bunch of places where we call .tp_alloc() directly, which is
very verbose. Add a macro that removes the boilerplate.

5d65ebb04b libdrgn: don't store language structures in one array
In the next change, we want to export languages to the public libdrgn
interface. I couldn't figure out any way to export array elements as
their own symbols. I'd also rather not export the drgn_languages array
indices as an enum because that would preclude ever having any sort of
language plugin support.

Instead, let's get rid of the drgn_languages array as it currently
exists and have separate drgn_language structures. This also allows us
to make a bunch of the C implementation functions static again. We keep
the language numbers so that we can store per-language data efficiently
(currently drgn_program::void_types and languages_py), as well as a
drgn_languages array to go from the language number to the struct
drgn_language. But, this is all internal and could be changed if we ever
support language plugins.

a4b9d68a8c Use GPL-3.0-or-later license identifier instead of GPL-3.0+
Apparently the latter is deprecated and the former is preferred.

8b264f8823 Update copyright headers to Facebook and add missing headers
drgn was originally my side project, but for awhile now it's also been
my work project. Update the copyright headers to reflect this, and add a
copyright header to various files that were missing it.

6c264b0eae libdrgn: add language to struct drgn_type
For types obtained from DWARF, we determine it from the language of the
CU. For other types, it can be specified manually or fall back to the
default (C). Then, we can use the language for operations where the type
is available.
