Summary:
Add fuzzy SymbolIndex, where identifier needn't match exactly.
The purpose for this is global autocomplete in clangd. The query will be a
partial identifier up to the cursor, and the results will be suggestions.
It's in include-fixer because:
- it handles SymbolInfos, actually SymbolIndex is exactly the right interface
- it's a good harness for lit testing the fuzzy YAML index
- (Laziness: we can't unit test clangd until reorganizing with a tool/ dir)
Other questionable choices:
- FuzzySymbolIndex, which just refines the contract of SymbolIndex. This is
an interface to allow extension to large monorepos (*cough*)
- an always-true safety check that Identifier == Name is removed from
SymbolIndexManager, as it's not true for fuzzy matching
- exposing -db=fuzzyYaml from include-fixer is not a very useful feature, and
a non-orthogonal ui (fuzziness vs data source). -db=fixed is similar though.

Summary:
Remove line number from Symbol identity.
For our purposes (include-fixer and clangd autocomplete), function overloads
within the same header should mostly be treated as a single combined symbol.
We may want to track individual occurrences (line number, full type info)
and aggregate this during mapreduce, but that's not done here.

Summary:
Add usage count to find-all-symbols.
FindAllSymbols now finds (most!) main-file usages of the discovered symbols.
The per-TU map output has NumUses=0 or 1 (only one use per file is counted).
The reducer aggregates these to find the number of files that use a symbol.
The NumOccurrences is now set to 1 in the mapper rather than being inferred by
the reducer, for consistency.
The idea here is to use NumUses for ranking: intuitively number of files that
use a symbol is more meaningful than number of files that include the header.

Instead of just using popularity, we also take into account how similar the
path of the current file is to the path of the header.
Our first approach is to get popularity into a reasonably small scale by taking
log2 (which is roughly intuitive to how humans would bucket popularity), and
multiply that with the number of matching prefix path fragments of the included
header with the current file.
Note that currently we do not take special care for unclean paths containing
"../" or "./".

The standalone tool only fixes the first one and we managed to bake that
assumption into the code :(
Also fix a crash when no header is found at all.

None of these tests actually require bash, they just have quoting bugs
when paths contain backslashes and colons. Fix them with the "%/T" lit
substitution variants.

Summary:
Previously, if we pass multiple files or a file pattern (e.g. /path/to/*.cc) to
include-fixer, include-fixer will apply all replacements to the first argument,
which probably causes crashes.
With this patch, include-fixer can process multiple files now.
Vim and Emacs integration are tested manually.

Summary:
No functional changes in this patch. It is a refactoring (pull out a
structure representing the symbol being queried).
This is a preparing step for inserting missing namespace qualifiers to all
instances of an unidentified symbol.

Summary:
The patch extends include-fixer's "-output-headers", and "-insert-headers"
command line options to make it dump more information (e.g. QualifiedSymbol),
so that vim-integration can add missing qualifiers.

Summary:
Currently, removing dot dot in header's path doesn't make include-fixer
minimize path correctly in some cases, for example, specify a relative search
path based on the build directory("-I../include/").
Besides, removing dot dot can break symbolic link directories. So don't
removing it for now.

If prefix search finds something where nothing can be nested under (e.g.
a variable or macro) don't add it to the result.
This is for cases like:
header.h:
extern int a;
file.cc:
namespace a {
SOME_MACRO
}
We will look up a::SOME_MACRO, which doesn't have any results. Then we
look up 'a' and find something before we ever look up just 'SOME_MACRO'.
With some basic filtering we can avoid this case.

This sorts based on the popularity of the header, not the symbol. If
there are mutliple matching symbols in one header we take the maximum
popularity for that header and deduplicate. If we know nothing we sort
lexicographically based on the header path.

This typically happens when the user didn't setup include paths correctly
and the fixer starts adding garbage includes. Avoid that. Disable the error
limit though, as we might hit that easily with missing includes and still
want to fix those cases.

This looks for find_all_symbols_db.yaml in all parent directories of the
source file (like we do for compile_commands.json) so we don't have to
pass the path manually.
