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.

LLDB is using LLVM's target-specific disassembler which is only available when
the respective LLVM target has been enabled in the build config.
This patch just skips the test if there is no arm64 target (and its

In 9ea6dd5cfa /
https://reviews.llvm.org/D88387 where I added skinny corefile
creation, I added new SB API and tried to manually update the hooks
for the reproducers. I missed a spot, and I should have used
lldb-instr to update the instrumentation automatically.
When assertions are turned off, the `llvm::Error` value created at the
start of this function is overwritten using the move-assignment
operator, but the success value is never checked. Whenever a TypeSystem
cannot be found or created, this can lead to lldb core dumping with:
Program aborted due to an unhandled Error:
Error value was Success. (Note: Success values must still be checked prior to being destroyed).
Fix this by not creating a `llvm::Error` value in advance, and directly
returning the result of `llvm::make_error` instead, whenever an error is
encountered.

These two tests, TestSkinnyCorefile.py and TestStackCorefile.py,
require a new debugserver on darwin systems to run correctly; for now,
skip them if the system debugserver is in use. There's no easy way to
test if the debugserver being used supports either of these memory
region info features. For end users, the fallback will be a full
corefile and that's not the worst thing, but for the tests it is a
problem.
The benefit of using assertIn is an improved error message when the
assertion fails:
AssertionError: False is not True
becomes
AssertionError: 'have ints 5 20 20 5' not found in '""'
Add a field to the qMemoryRegionInfo packet where the remote stub
can describe the type of memory -- heap, stack. Keep track of
memory regions that are stack memory in lldb. Add a new "--style

included in the corefile.

This patch should fix the use-after-free error that was brought up by
the LLDB ASAN Green Dragon bot.
This is caused because the `StringRef` object was acquired too early
before being use and by the underlying memory was modified which caused
it to point to null memory.
Fetching back the string reference close to its usage location should
fix the issue.

This test is specifying the lldb log channel via `ll""db` which only really works
because the command parser ends up parsing that as `lldb`. Just putting the
channel name in quotes is enough to avoid the lldb command substitution and
doesn't rely on this weird parser behaviour.
Some files still contained the old University of Illinois Open Source
Licence header. This patch replaces that with the Apache 2 with LLVM

LLDB evaluates some utility expression to update the Objective-C class list that
ends up calling function such as `free` or `objc_copyRealizedClassList_nolock`.
This adds a test that just tries to define our own bogus version of
`objc_copyRealizedClassList_nolock`. It just tests that LLDB doesn't crash as we
currently don't have a way to tell LLDB to look for the function in a specific
library.

We recently had an issue where a user declared a `Class::free` function which
then got picked up by accident by the expression evaluator when calling
`::free`. This was due to a too lax filter in the DWARFIndex (which was fixed by
https://reviews.llvm.org/D73191 ). This broke the Objective-C utility expression
that is trying to update the Objective-C class list (which is calling `:;free`).
This adds a regression test for situations where we have a bunch of functions
defined that share the name of the global functions that this utility function
calls. None of them are actually conflicting with the global functions we are
trying to call (they are all in namespaces, objects or classes).

Sync the mode constants used to drive vFile:open requests with these

Modify OpenOptions enum to open the future path into synchronizing
vFile:open bits with GDB. Currently, LLDB and GDB use different flag
models effectively making it impossible to match bits. Notably, LLDB
uses two bits to indicate read and write status, and uses union of both
for read/write. GDB uses a value of 0 for read-only, 1 for write-only
and 2 for read/write.
In order to future-proof the code for the GDB variant:
1. Add a distinct eOpenOptionReadWrite constant to be used instead
of (eOpenOptionRead | eOpenOptionWrite) when R/W access is required.
2. Rename eOpenOptionRead and eOpenOptionWrite to eOpenOptionReadOnly
and eOpenOptionWriteOnly respectively, to make it clear that they
do not mean to be combined and require update to all call sites.
3. Use the intersection of all three flags when matching against
the three possible values.
This commit does not change the actual bits used by LLDB.
