Georgii Rymar 47369e194a [yaml2obj][obj2yaml] - Teach tools to work with regular archives.
This teaches obj2yaml to dump valid regular (not thin) archives.
This also teaches yaml2obj to recognize archives YAML descriptions,
what allows to craft all different kinds of archives (valid and broken ones).

Xing GUO 3cda698723 [obj2yaml] Stop parsing the debug_str section when it encounters a string without the null terminator.
When obj2yaml encounters a string without the null terminator, it should
stop parsing the debug_str section. This patch addresses comments in
[D86867](https://reviews.llvm.org/D86867#inline-803291).

Xing GUO 3c5758964c [macho2yaml] Refactor the DWARF section dumpers.
This patch refactors the DWARF section dumpers. When dumping a DWARF
section, if the DWARF parser fails to parse the section, we will dump it
as a raw content section. This patch also fixes a bug in
DWARFYAML::Data::isEmpty(). Finally, a test case that tests dumping the
__debug_aranges section is added.

Igor Kudrin dcff3961c2 [DWARF] Return Error from DWARFDebugArangeSet::extract().
This helps to detect and report parsing errors better.
The patch follows the ideas of LLDB's patches D59370 and D59381.

It adds tests for valid and some invalid cases. More checks and
tests to come. Note that the patch fixes validation of the Length
field because the value does not include the field itself.

The existing users are updated to show the error messages.

George Rimar 224816ba16 Recommit r366052 "[obj2yaml] - Rework tool's error reporting logic for ELF target."
No changes, LLD code was updated in r366057.

Original commit message:

ELF.h contains two getSymbol methods
which seems to be used only from obj2yaml.

One of these methods calls another, which in turn
contains untested error message which doesn't
provide enough information.

Problem is that after improving only just that message,
obj2yaml will not show it,
("Error reading file: yaml: Invalid data was
encountered while parsing the file" message will be shown instead),
because internal errors handling of tool is based on ErrorOr<> class which
stores a error code and as a result can only show a predefined error string, what
actually isn't very useful.

In this patch, I rework obj2yaml's error reporting system
for ELF targets to use Error  Expected<> classes.
Also, I improve the error message produced
by getSymbol for demonstration of the new functionality.

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
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.

Rafael Espindola c398e67fed Use delegation instead of inheritance.
This changes DwarfContext to delegate to DwarfObject instead of having
pure virtual methods.

With this DwarfContextInMemory is replaced with an implementation of
DwarfObject that is local to a .cpp file.

Derek Schuff d3d84fdda1 [WebAssembly] Improve support for WebAssembly binary format
Mostly this change adds support converting to and from
YAML which will allow us to write more test cases for
the WebAssembly MC and lld ports.

Better support for objdump, readelf, and nm will be in
followup CLs.

I had to update the two wasm test binaries because they
used the old style 'name' section which is no longer
supported.
