The isprint libc function was used to determine if the key code
represents a printable character. The problem is that the specification
leaves the behavior undefined if the key is not representable as an
unsigned char, which is the case for many ncurses keys. This patch adds
and explicit check for this undefined behavior and make it consistent.
The llvm::isPrint function didn't work correctly for some reason, most
likely because it takes a char instead of an int, which I guess makes it
unsuitable for checking ncurses key codes.

This patch adds a breakpoints window that lists all breakpoints and
breakpoints locations. The window is implemented as a tree, where the
first level is the breakpoints and the second level is breakpoints
locations.
The tree delegate was hardcoded to only draw when there is a process,
which is not necessary for breakpoints, so the relevant logic was
abstracted in the TreeDelegateShouldDraw method.

This patch adds a new method SubSurface to the Surface class. The method
returns another surface that is a subset of this surface. This is
important to further abstract away drawing from the ncurses objects. For
instance, fields could previously be drawn on subpads only but can now
be drawn on any surface. This is needed to create the file search
dialogs and similar functionalities.
There is an opportunity to refactor window drawing in general using
surfaces, but we shall consider this separately later.

This patch adds initial support for forms for the LLDB GUI. The currently
supported form elements are Text fields, Integer fields, Boolean fields, Choices
fields, File fields, Directory fields, and List fields.
A form can be created by subclassing FormDelegate. In the constructor, field
factory methods can be used to add new fields, storing the returned pointer in a
member variable. One or more actions can be added using the AddAction method.
The method takes a function with an interface void(Window &). This function will
be executed whenever the user executes the action.
Example form definition:
```lang=cpp
class TestFormDelegate : public FormDelegate {
public:
TestFormDelegate() {
m_text_field = AddTextField("Text", "The big brown fox.");
m_file_field = AddFileField("File", "/tmp/a");
m_directory_field = AddDirectoryField("Directory", "/tmp/");
m_integer_field = AddIntegerField("Number", 5);
std::vector<std::string> choices;
choices.push_back(std::string("Choice 1"));
choices.push_back(std::string("Choice 2"));
choices.push_back(std::string("Choice 3"));
choices.push_back(std::string("Choice 4"));
choices.push_back(std::string("Choice 5"));
m_choices_field = AddChoicesField("Choices", 3, choices);
m_bool_field = AddBooleanField("Boolean", true);
TextFieldDelegate default_field =
TextFieldDelegate("Text", "The big brown fox.");
m_text_list_field = AddListField("Text List", default_field);
AddAction("Submit", [this](Window &window) { Submit(window); });
}
void Submit(Window &window) { SetError("An example error."); }

`vwprintw` is (in theory) using the `arargs.h` va_list while `vw_printw` is

This is an NFC cleanup.
Many of the API's that returned BreakpointOptions always returned valid ones.
Internally the BreakpointLocations usually have null BreakpointOptions, since they
use their owner's options until an option is set specifically on the location.
So the original code used pointers & unique_ptr everywhere for consistency.
But that made the code hard to reason about from the outside.
This patch changes the code so that everywhere an API is guaranteed to
return a non-null BreakpointOption, it returns it as a reference to make
that clear.
It also changes the Breakpoint to hold a BreakpointOption
member where it previously had a UP. Since we were always filling the UP
in the Breakpoint constructor, having the UP wasn't helping anything.

After 5419b67137 (which is `[SimplifyCFG] Update FoldTwoEntryPHINode to handle and/or of select and binop equally`), this uninitialized value is detected by msan.
`ValueObject.h` contains the `ValueObject::ValueObjectManager` type which is
just a typedef for the ClusterManager that takes care of the whole ValueObject
memory management. However, there is also `ValueObjectManager` defined in the
same header which is only used in the curses UI implementation and consists
mostly of dead and completely untested code.
This code been around since a while (it was added in 2016 as
8369b28da0), so I think we shouldn't just revert
the whole patch.
Instead this patch just moves the class to its own header that it isn't just
hiding in the ValueObject header and renames it to `ValueObjectUpdater` that it
at least has a unique name (which I hope also slightly better reflects the
purpose of this class). I also deleted all the dead code branches and functions.

This reverts commit a01b26fb51, because it
breaks the "finish" command in some way -- the command does not
terminate after it steps out, but continues running the target. The
exact blast radius is not clear, but it at least affects the usage of
the "finish" command in TestGuiBasicDebug.py. The error is *not*
gui-related, as the same issue can be reproduced by running the same
steps outside of the gui.
There is some kind of a race going on, as the test fails only 20% of the
time on the buildbot.
Currently, the interpreter's context is not updated until a command is executed.
This has resulted in the behavior of SB-interface functions and some commands
depends on previous user actions. The interpreter's context can stay uninitialized,
point to a currently selected target, or point to one of previously selected targets.
This patch removes any usages of CommandInterpreter::UpdateExecutionContext.
CommandInterpreter::HandleCommand* functions still may override context temporarily,
but now they always restore it before exiting. CommandInterpreter saves overriden
contexts to the stack, that makes nesting commands possible.
Added test reproduces one of the issues. Without this fix, the last assertion fails
because interpreter's execution context is empty until running "target list", so,
the value of the global property was updated instead of process's local instance.
