This has no uses and the ValueObjectDynamicValue already tracks
its ownership through the parent it is passed when made. I can't
find any vestiges of the use of this API, maybe it was from some
earlier design?
Resetting the backing ivar was the only job the destructor did, so I
set that to default as well.

The new key/value pairs that are added to each module's stats are:
"debugInfoByteSize": The size in bytes of debug info for each module.
"debugInfoIndexTime": The time in seconds that it took to index the debug info.
"debugInfoParseTime": The time in seconds that debug info had to be parsed.
At the top level we add up all of the debug info size, parse time and index time with the following keys:
"totalDebugInfoByteSize": The size in bytes of all debug info in all modules.
"totalDebugInfoIndexTime": The time in seconds that it took to index all debug info if it was indexed for all modules.
"totalDebugInfoParseTime": The time in seconds that debug info was parsed for all modules.

Add a Communication::WriteAll() that resumes Write() if the initial call
did not write all data. Use it in GDBRemoteCommunication when sending
packets in order to fix handling partial writes (i.e. just resume/retry
them rather than erring out). This fixes LLDB failures when writing
large packets to a pty.

This patch deals with ObjectFile, ObjectContainer and OperatingSystem
plugins. I'll convert the other types in separate patches.
In order to enable piecemeal conversion, I am leaving some ConstStrings
in the lowest PluginManager layers. I'll convert those as the last step.

When printing names in lldb on windows these names contain the full type information while on linux only the name is contained.
This change introduces a flag in the Microsoft demangler to control if the type information should be included.
With the flag enabled demangled name contains only the qualified name, e.g:
without flag -> with flag
int (*array2d)[10] -> array2d
int (*abc::array2d)[10] -> abc::array2d
const int *x -> x
For globals there is a second inconsistency which is not yet addressed by this change. On linux globals (in global namespace) are prefixed with :: while on windows they are not.

There is no reason why this function should be returning a ConstString.
While modifying these files, I also fixed several instances where
GetPluginName and GetPluginNameStatic were returning different strings.
I am not changing the return type of GetPluginNameStatic in this patch, as that
would necessitate additional changes, and this patch is big enough as it is.

When we know the bounds of the array, print any embedded nuls instead of
treating them as terminators. An exception to this rule is made for the
nul character at the very end of the string. We don't print that, as
otherwise 99% of the strings would end in \0. This way the strings
usually come out the same as how the user typed it into the compiler
(char foo[] = "with\0nuls"). It also matches how they come out in gdb.
This resolves a FIXME left from D111399, and leaves another FIXME for dealing
with nul characters in "escape-non-printables=false" mode. In this mode the
characters cause the entire summary string to be terminated prematurely.

.. and reduce the scope of others. They don't follow llvm coding
standards (which say they should be used only when the same effect
cannot be achieved with the static keyword), and they set a bad example.
Update GetRegisterInfoByName() methods to support getting registers
by a generic name independently of alt_name entries in the register
context. This makes it possible to use generic names when interacting
with gdbserver (that does not supply alt_names). It also makes it
possible to remove some of the duplicated information from register
context declarations and/or use alt_names for another purpose.

This change adds save-core functionality into the ObjectFileELF that enables
saving minidump of a stopped process. This change is mainly targeting Linux
running on x86_64 machines. Minidump should contain basic information needed
to examine state of threads, local variables and stack traces. Full support
for other platforms is not so far implemented. API tests are using LLDB's
MinidumpParser.
This relands commit aafa05e, reverted in 1f986f6.

This patch adds a new type of reusable UI components. Searcher Windows
contain a text field to enter a search keyword and a list of scrollable
matches are presented. The target match can be selected and executed
which invokes a user callback to do something with the match.
This patch also adds one searcher delegate, which wraps the common
command completion searchers for simple use cases.

Module::LookupInfo's constructor currently goes over supported languages
trying to figure out the best way to search for a symbol name. This
seems like a great candidate for refactoring. Specifically, this is work
that can be delegated to language plugins.
Once again, the goal here is to further decouple plugins from
non-plugins. The idea is to have each language plugin take a name and
give you back some information about the name from the perspective of
the language. Specifically, each language now implements a
`GetFunctionNameInfo` method which returns an object of type
`Language::FunctionNameInfo`. Right now, it consists of a basename,
a context, and a FunctionNameType. Module::LookupInfo's constructor will
call `GetFunctionNameInfo` with the appropriate language plugin(s) and
then decide what to do with that information. I have attempted to maintain
existing behavior as best as possible.
A nice side effect of this change is that lldbCore no longer links
against the ObjC Language plugin.

This patch adds a new key ALt+Enter key combination to form windows.
Once invoked, the first action is executed without having to navigate to

Field exit callbacks are now also invoked on validation to support this
aforementioned key combination.
One concern for this key combination is its potential use by the window
manager of the host. I am not sure if this will be a problem, but it is
worth putting in consideration.

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.

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.
