Luboš Luňák 8739445e32 [lldb] force full gui redraw on Ctrl+L
As is common with curses apps, this allows to redraw everything
in case something corrupts the screen. Apparently key modifiers
are difficult with curses (curses FAQ it "doesn't do that"),
thankfully Ctrl+key are simply control characters, so it's
(ascii & 037) => 12.

Luboš Luňák 47d2c7cd5d [lldb] remove somewhat dangerous 'd'(etach) and 'k'(ill) shortcuts
'd' would be much better used for up/down shortcuts, and this also removes
the possibility of ruining the whole debugging session by accidentally
hitting 'd' or 'k'. Also change menu to have both 'detach and resume'
and 'detach suspended' to make it clear which one is which. See
discussion at https://reviews.llvm.org/D68541 .

Jonas Devlieghere cee60bbf41 [lldb] Remove the user-defined copy-ctor in ConstString
ConstString is essentially trivially copyable yet it has a user defined
copy constructor that copies its one member pointer. Remove it so it
qualifies as trivial in the eyes of the compiler.

This also fixes two unused variable warnings now that the compiler knows
that the constructor has no side-effects.

Jonas Devlieghere 06412dae82 [lldb] Use std::make_unique<> (NFC)
Update the rest of lldb to use std::make_unique<>. I used clang-tidy to
automate this, which probably missed cases that are wrapped in ifdefs.

Raphael Isemann f5eaa2afe2 [lldb] Replace std::isprint/isspace with llvm's locale-independent version
Summary:
LLVM is using its own isPrint/isSpace implementation that doesn't change depending on the current locale. LLDB should do the same
to prevent that internal logic changes depending on the set locale.

Konrad Kleine eaebcbc679 [lldb] NFC remove DISALLOW_COPY_AND_ASSIGN
Summary:
This is how I applied my clang-tidy check (see
https://reviews.llvm.org/D80531) in order to remove
`DISALLOW_COPY_AND_ASSIGN` and have deleted copy ctors and deleted
assignment operators instead.

```
lang=bash
grep DISALLOW_COPY_AND_ASSIGN /opt/notnfs/kkleine/llvm/lldb -r -l | sort | uniq > files

for i in $(cat files);
do
  clang-tidy \
    --checks="-*,modernize-replace-disallow-copy-and-assign-macro" \
    --format-style=LLVM \
    --header-filter=.* \
    --fix \
    -fix-errors \
    $i;
done
```

Raphael Isemann 808142876c [lldb][NFC] Fix all formatting errors in .cpp file headers
Summary:
A *.cpp file header in LLDB (and in LLDB) should like this:
```
//===-- TestUtilities.cpp -------------------------------------------------===//
```
However in LLDB most of our source files have arbitrary changes to this format and
these changes are spreading through LLDB as folks usually just use the existing
source files as templates for their new files (most notably the unnecessary
editor language indicator `-*- C++ -*-` is spreading and in every review
someone is pointing out that this is wrong, resulting in people pointing out that this
is done in the same way in other files).

This patch removes most of these inconsistencies including the editor language indicators,
all the different missing/additional '-' characters, files that center the file name, missing
trailing `===//` (mostly caused by clang-format breaking the line).

Pavel Labath 532290e69f [lldb] s/FileSpec::Equal/FileSpec::Match
Summary:
The FileSpec class is often used as a sort of a pattern -- one specifies
a bare file name to search, and we check if in matches the full file
name of an existing module (for example).

These comparisons used FileSpec::Equal, which had some support for it
(via the full=false argument), but it was not a good fit for this job.

For one, it did a symmetric comparison, which makes sense for a function
called "equal", but not for typical searches (when searching for
"/foo/bar.so", we don't want to find a module whose name is just
"bar.so"). This resulted in patterns like:
    if (FileSpec::Equal(pattern, file, pattern.GetDirectory()))
which would request a "full" match only if the pattern really contained
a directory. This worked, but the intended behavior was very unobvious.

On top of that, a lot of the code wanted to handle the case of an
"empty" pattern, and treat it as matching everything. This resulted in
conditions like:
    if (pattern && !FileSpec::Equal(pattern, file, pattern.GetDirectory())
which are nearly impossible to decipher.

This patch introduces a FileSpec::Match function, which does exactly
what most of FileSpec::Equal callers want, an asymmetric match between a
"pattern" FileSpec and a an actual FileSpec. Empty paterns match
everything, filename-only patterns match only the filename component.

I've tried to update all callers of FileSpec::Equal to use a simpler
interface. Those that hardcoded full=true have been changed to use
operator==. Those passing full=pattern.GetDirectory() have been changed
to use FileSpec::Match.

There was also a handful of places which hardcoded full=false. I've
changed these to use FileSpec::Match too. This is a slight change in
semantics, but it does not look like that was ever intended, and it was
more likely a result of a misunderstanding of the "proper" way to use
FileSpec::Equal.

[In an ideal world a "FileSpec" and a "FileSpec pattern" would be two
different types, but given how widespread FileSpec is, it is unlikely
we'll get there in one go. This at least provides a good starting point
by centralizing all matching behavior.]

Raphael Isemann 7caa17caf8 [lldb][NFC] Move Curses interface implementation to own file
Summary:
The IOHandler class source file is currently around 4600 LOC. However only 200
of these lines are concerned with the actual IOHandler class and the rest are the
implementations for Editline, IOHandlerConfirm and the Curses interface. All these
large features also cause that the IOHandler (which is in Core) has a large set of dependencies
on other parts of LLDB.

This patch splits out the code for the curses interface into its own file. This way
the simple IOHandler code is no longer buried in-between much larger functionalities.

Next up is splitting out the other IOHandlers into their own files and then move them
to more appropriate parts of LLDB.
