This patch removes the two variant of StringExtractor::GetStringRef that
return (non-)const references to std::string. The non-const one was
being abused to reinitialize the StringExtractor and its uses are
replaced by calls to the copy asignment operator. The const variant was
refactored to return an actual llvm::StringRef.

The implementation of this function was obviously incorrect, as the

Summary:
Explicitly code-sign the LLDB.framework copy of debugserver in the build-tree. This is necessary, because the Xcode-specific logic in `llvm_codesign` [1] has the side-effect that Xcode code-signs after post-build steps (here: after copying debugserver over into the framework). The special case for Xcode was necessary to avoid double-signing errors in the past (see D55116 and D55816).

rL357954 did increase `packet-timeout` 1sec -> 5secs. Which is IMO about the
maximum timeout reasonable for regular use. But for testsuite I think the
timeout should be higher as the testsuite runs in parallel and it can be run
even on slow hosts and with other load (moreover if it runs on some slow arch).
I have chosen 60 secs, that should be enough hopefully. Larger value could
make debugging with hanging `lldb-server` annoying.
This patch was based on this testsuite timeout:

This patch replaces explicit calls to log::Printf with the new LLDB_LOGF
macro. The macro is similar to LLDB_LOG but supports printf-style format
strings, instead of formatv-style format strings.
So instead of writing:
if (log)
log->Printf("%s\n", str);
You'd write:
LLDB_LOG(log, "%s\n", str);
This change was done mechanically with the command below. I replaced the
spurious if-checks with vim, since I know how to do multi-line
replacements with it.

Summary:
SymbolFile classes are responsible for creating CompileUnit instances
and they already need to have a notion of the id<->CompileUnit mapping
(because of APIs like ParseCompileUnitAtIndex). However, the
SymbolVendor has remained as the thing responsible for caching created
units (which the SymbolFiles were calling via convoluted constructs like
"m_obj_file->GetModule()->GetSymbolVendor()->SetCompileUnitAtIndex(...)").
This patch moves the responsibility of caching the units into the
SymbolFile class. It does this by moving the implementation of
SymbolVendor::{GetNumCompileUnits,GetCompileUnitAtIndex} into the
equivalent SymbolFile functions. The SymbolVendor functions become just
a passthrough much like the rest of SymbolVendor.
The original implementations of SymbolFile::GetNumCompileUnits is moved
to "CalculateNumCompileUnits", and are made protected, as the "Get"
function is the external api of the class.
SymbolFile::ParseCompileUnitAtIndex is made protected for the same
reason.
This is the first step in removing the SymbolVendor indirection, as
proposed in
<http://lists.llvm.org/pipermail/lldb-dev/2019-June/015071.html>. After
removing all interesting logic from the SymbolVendor class, I'll proceed
with removing the indirection itself.

Summary:
We can always build debugserver, but we can't always sign it to be useable for testing. `LLDB_USE_SYSTEM_DEBUGSERVER` should only tell whether or not the system debugserver should be used for testing.
The old behavior complicated the logic around debugserver a lot. The new logic sorts out most of it.
Please note that this patch is in early stage and needs some more testing. It should not affect platfroms other than Darwin. It builds on Davide's approach to validate the code-signing identity at configuration time.

Summary:
There's a number of requirements for installing LLDB on macOS that are untypical for LLVM projects: use special install-prefix for LLDB.framework, ship headers and tools as framework resources, patch RPATHs, externalize debug-info to dSYM's and strip binaries with `-ST`. For some of it we could use `llvm_externalize_debuginfo()` in the past and just add special cases. However, this complicates the code for all projects and comes with the major drawback, that it adds all these actions at build-time, i.e. dSYM creation and stripping take a lot of time and don't make sense at build-time.
LLVM's distribution mechanism (https://llvm.org/docs/BuildingADistribution.html) appears to be the natural candidate to install LLDB. Based on D64399 (enable in standalone builds), this patch integrates framework installation with the distribution mechanism and adds custom stripping flags and dSYM creation at install-time. Unlike the abandoned D61952, it leaves build-tree binaries untouched, so there's no side-effects on testing. Potential install-order issues must be handled externally.
Please let me know what you think, while I run a few more tests and add remarks+documentation.

D55859 <https://reviews.llvm.org/D55859> has no effect for some of the
testcases so this patch extends it even for (all?) other testcases known to me.
LLDB was failing when LLDB prints errors reading system debug infos
(`*-debuginfo.rpm`, DWZ-optimized) which should never happen as LLDB testcases
should not be affected by system debug infos.
`lldb/packages/Python/lldbsuite/test/api/multithreaded/driver.cpp.template` is
using only SB API which does not expose `ModuleList` so I had to call
`HandleCommand()` there.
`lldb-test.cpp` could also use `HandleCommand` and then there would be no need
for `ModuleListProperties::SetEnableExternalLookup()` but I think it is cleaner
with API and not on based on text commands.

Problem discovered in the breakpoint lit test, but probably exists in others.
lldb-test splits lines on LF. Input files that are CR+LF separated (as is
common on Windows) then resulted in commands being sent to LLDB that ended
in CR, which confused the command interpreter.
This could be fixed at different levels:
1. Treat '\r' like a tab or space in the argument splitter.
2. Fix the line splitters (plural) in lldb-test.
3. Normalize the test files to LF only.
If we did only 3, I'd expect similar problems to recur, so this patch does
1 and 2. I may also do 3 in a separate patch later, but that's tricky
because I believe we have some input files that MUST use CR+LF.

Summary:
Modify the way LLDB.framework tools are collected. This allows for better fine-tuning of the install behavior downstream. Each target calls `lldb_add_to_framework()` individually. When entering the function, the target exists and we can tweak its very own post-build and install steps. This was not possible with the old `LLDB_FRAMEWORK_TOOLS` approach.
No function change otherwise.
This is a reduced follow-up from the proposal in D61952.

This is the command I ran and I to fix and format the code base:

-checks='-*,modernize-use-nullptr' \
-fix ~/dev/llvm-project/lldb/.* \
-format \
-style LLVM \
-p ~/llvm-builds/debug-ninja-gcc

NOTE: There were also changes to `llvm/utils/unittest` but I did not
include them because I felt that maybe this library shall be updated in
isolation somehow.
NOTE: I know this is a rather large commit but it is a nobrainer in most
parts.
