Bruce Mitchener 27801f4ff7 Reuse native curses(8) library on NetBSD
Summary:
The reason for it is limit of detecting ncurses on various systems. For
example, Ubuntu ships with <curses.h> and linkage from <ncurses.h>, <ncurses.h>
isn't detected by CMake. Detecting `<curses.h>` on NetBSD is reusing
conflicting header from the host curses(8) and pkgsrc's ncurses library.

ncurses ships on most (till conflicting) systems with curses.h. On NetBSD it
might be conflicting, so the ncurses headers are installed with pkgsrc to a
subdirectory "ncurses/".

Patch by Kamil Rytarowski. Thanks!

Jason Molenda 9c077cf33d Change ModuleList::GetSharedModule so that it will reject "stub
libraries" altogether.  On Mac/iOS, these are libraries which have
a UUID and nlist records but no text or data.  If one of these
gets into the global module list, every time we try to search
for a given filename/arch/UUID, we'll get this stub library back.
We need to prevent them from getting added to the module list
altogether.

I thought about doing this down in ObjectFileMachO -- just rejecting
the file as a valid binary file altogether -- but Greg didn't want
to take that hard line approach at this point, he wanted to keep
the ability for lldb to read one of these if someone wanted to in
the future.

Siva Chandra 9ac7a6c51f [SBValue] Add a method GetNumChildren(uint32_t max)
Summary:
Along with this, support for an optional argument to the "num_children"
method of a Python synthetic child provider has also been added. These have
been added with the following use case in mind:

Synthetic child providers currently have a method "has_children" and
"num_children". While the former is good enough to know if there are
children, it does not give any insight into how many children there are.
Though the latter serves this purpose, calculating the number for children
of a data structure could be an O(N) operation if the data structure has N
children. The new method added in this change provide a middle ground.
One can call GetNumChildren(K) to know if a child exists at an index K
which can be as large as the callers tolerance can be. If the caller wants
to know about children beyond K, it can make an other call with 2K. If the
synthetic child provider maintains state about it counting till K
previosly, then the next call is only an O(K) operation. Infact, all
calls made progressively with steps of K will be O(K) operations.

REPLs can also do code completion.  The REPL class allows its subclasses to
implement the language-specific functionality without having to know about the
IOHandler-specific internals.

Also added a PluginManager-based way of getting to a REPL given a language and
a target.

Also brought in some utility code and expression options that are useful for
REPLs, such as line offsets for expressions, ANSI terminal coloring of errors,
and a few IOHandler convenience functions.

Todd Fiala 7df337f85c ArchSpec: fix unintentional promotion of unspecified unknowns to specified unknowns
* ArchSpec::MergeFrom() would erroneously promote an unspecified
  unknown to a specified unknown when both the ArchSpec and the merged
  in ArchSpec were both unspecified unknowns. This no longer happens,
  which fixes issues with global module cache lookup in some
  situations.

* Added ArchSpec::DumpTriple(Stream&) that now properly prints
  unspecified unknowns as '*' and specified unknows as 'unknown'.
  This makes it trivial to tell the difference between the two.
  Converted printing code over ot using DumpTriple() rather than
  building from scratch.

Jason Molenda 8825c5c9b4 Re-commit the (fixed) changes from r248985 which were reverted by Pavel
when they introduced android testsuite regressions.  Pavel has run the
testsuite against the updated patch and it completes cleanly now.

The original commit message:


Fixing a subtle issue on Mac OS X systems with dSYMs (possibly
introduced by r235737 but I didn't look into it too closely).

A dSYM can have a per-UUID plist in it which tells lldb where
to find an executable binary for the dSYM (DBGSymbolRichExecutable)
- other information can be included in this plist, like how to
remap the source file paths from their build pathnames to their
long-term storage pathnames.

This per-UUID plist is a unusual; it is used probably exclusively
inside apple with our build system.  It is not created by default
in normal dSYMs.

The problem was like this:

  1. lldb wants to find an executable, given only a UUID
     (this happens when lldb is doing cross-host debugging
      and doesn't have a copy of the target system's binaries)

  2. It eventually calls LocateMacOSXFilesUsingDebugSymbols
     which does a spotlight search for the dSYM on the local
     system, and failing that, tries the DBGShellCommands
     command to find the dSYM.

  3. It gets a dSYM.  It reads the per-UUID plist in the dSYM.
     The dSYM has a DBGSymbolRichExecutable kv pair pointing to
     the binary on a network filesystem.

  4. Using the binary on the network filesystem, lldb now goes
     to find the dSYM.

  5. It starts by looking for a dSYM next to the binary it found.

  6. lldb is now reading the dSYM over a network filesystem,
     ignoring the one it found on its local filesystem earlier.

Everything still *works* but it's much slower.

This would be a tricky one to write up in a testsuite case;
you really need the binary to not exist on the local system.
And LocateMacOSXFilesUsingDebugSymbols will only compile on
Mac OS X - even if I found a way to write up a test case, it
would not run anywhere but on a mac.

One change Greg wanted while I was touching this code was to
have LocateMacOSXFilesUsingDebugSymbols (which could be asked
to find a binary OR find a dSYM) to instead return a ModuleSpec
with the sum total of everything it could find.  This
change of passing around a ModuleSpec instead of a FileSpec
was percolated up into ModuleList::GetSharedModule.

The changes to LocateMacOSXFilesUsingDebugSymbols look larger
than they really are - there's a lot of simple whitespace changes
in there.

I ran the testsuites on mac, no new regressions introduced
