We just forget to check for interrupt while waiting for the answer to the prompt. But if we are in the interrupt state then the lower
layers of the EditLine code just eat all characters so we never get out of the query prompt. You're pretty much stuck and have to kill lldb.
The solution is to check for the interrupt. The patch is a little bigger because where I needed to check the Interrupt state I only
had the ::EditLine object, but the editor state is held in lldb's EditLine wrapper, so I had to do a little work to get my hands on it.
This is an ongoing series of commits that are reformatting our Python
code. Reformatting is done with `black` (23.1.0).
If you end up having problems merging this commit because you have made
changes to a python file, the best way to handle that is to run `git
checkout --ours <yourfile>` and then reformat it with black.

Eliminate boilerplate of having each test manually assign to `mydir` by calling
`compute_mydir` in lldbtest.py.

When I run a lldb command that uses filename completion, if I enter a string
that is not only a filename but also a string with a non-file name string added,
such as "./" that is relative path string , it will crash as soon as I press the
[Tab] key. For example, debugging an executable file named "hello" that is
compiled from a file named "hello.c" , and I’ll put a breakpoint on line 3 of
hello.c.
```
$ lldb ./hello
(lldb) breakpoint set --file hello.c --line 3
```
This is not a problem, but if I set "--file ./hello." and then press [Tab] key
to complete file name, lldb crashes.
```
$ lldb ./hello
(lldb) breakpoint set --file ./hello.terminate called after throwing an instance of 'std::out_of_range'
what(): basic_string::substr: __pos (which is 8) > this->size() (which is 7)
```
The crash was caused because substr() (in lldb/source/Host/common/Editline.cpp)
cut out string which size is user's input string from the completion string.
I modified the code that erase the user's intput string from current line and
then add the completion string.

Following tests have been failing randomly on LLDB Arm and AArch64 Linux
builtbots:
TestMultilineNavigation.py
TestMultilineCompletion.py
TestIOHandlerCompletion.py
TestGuiBasic.py
I have increased allocated CPU resources to these bots but it has not
improved situation to an acceptable level. This patch marks them as
skipped on Arm/AArch64 for now.
This is relanding D81001. The patch originally failed as on newer editline
versions it seems CC_REFRESH will move the cursor to the start of the line via
\r and then back to the original position. On older editline versions like
the one used by default on macOS, CC_REFRESH doesn't move the cursor at all.
As the patch changed the way we handle tab completion (previously we did
REDISPLAY but now we're doing CC_REFRESH), this caused a few completion tests
to receive this unexpected cursor movement in the output stream.
This patch updates those tests to also accept output that contains the specific
cursor movement commands (\r and then \x1b[XC). lldbpexpect.py received an
utility method for generating the cursor movement escape sequence.
Original summary:
I implemented autosuggestion if there is one possible suggestion.
I set the keybinds for every character. When a character is typed, Editline::TypedCharacter is called.
Then, autosuggestion part is displayed in gray, and you can actually input by typing C-k.
Editline::Autosuggest is a function for finding completion, and it is like Editline::TabCommand now, but I will add more features to it.
Testing does not work well in my environment, so I can't confirm that it goes well, sorry. I am dealing with it now.

Summary: Moves lldbsuite tests to lldb/test/API.
This is a largely mechanical change, moved with the following steps:
```
rm lldb/test/API/testcases
mkdir -p lldb/test/API/{test_runner/test,tools/lldb-{server,vscode}}
mv lldb/packages/Python/lldbsuite/test/test_runner/test lldb/test/API/test_runner
for d in $(find lldb/packages/Python/lldbsuite/test/* -maxdepth 0 -type d | egrep -v "make|plugins|test_runner|tools"); do mv $d lldb/test/API; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-vscode -maxdepth 1 -mindepth 1 | grep -v ".py"); do mv $d lldb/test/API/tools/lldb-vscode; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-server -maxdepth 1 -mindepth 1 | egrep -v "gdbremote_testcase.py|lldbgdbserverutils.py|socket_packet_pump.py"); do mv $d lldb/test/API/tools/lldb-server; done
```
lldb/packages/Python/lldbsuite/__init__.py and lldb/test/API/lit.cfg.py were also updated with the new directory structure.
