Benjamin Kramer 1d3a91a682 [include-fixer] Don't return a correction if the header insertion failed.
This is could happen in cases involving macros and we don't want to
return an invalid fixit for it or a confusing error message with no
fixit.

Manuel Klimek a47515ec4a Improve include fixer's ranking by taking the paths into account.
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 "./".

David Blaikie e83806be32 Reapply "Fix for shared_ptrification in Clang"
Aleksey Shlyapnikov pointed out the memory leak I'd introduced, so
recommitted the clang change with a fix for that.

This reapplies r291186, reverted in r291251.

Haojian Wu c99f72868d [include-fixer] Support processing multiple files in one run.
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.

Haojian Wu adedac68dc [include-fixer] Correct nested class search for identifiers with scoped information
Summary:
include-fixer will firstly try to use scoped namespace context information to
search identifier. However, in some cases, it's unsafe to do nested class
search, because it might treat the identifier as a nested class of scoped
namespace.

Given the following code, and the symbol database only has two classes: "foo" and
"b::Bar".

    namespace foo { Bar t; }

Before getting fixing, include-fixer will never search "Bar" symbol.
Because it firstly tries to search "foo::Bar", there is no "Bar" in foo namespace,
then it finds "foo" in database finally. So it treats "Bar" is a nested class
of "foo".

Summary:
This is an initial version of fixing namespace issues by adding missing
namespace qualifiers to an unidentified symbol.

This version only fixes the first discovered unidentified symbol.
In the long run, include-fixer should fix all unidentified symbols
with a same name at one run.

Currently, it works on command-line tool. The vim integration is not
implemented yet.

Benjamin Kramer 6b5160a369 [include-fixer] Don't insert #includes if a fatal error occurred.
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.

Benjamin Kramer ad93500c52 [include-fixer] Work around partial names in both directions.
We already handled the case where we had a nested name specifier where
parts from the beginning don't get a callback, also handle the case
where the end doesn't get a callback. This happens with function calls
in unknown namespaces.

The way we do this for now based on character data is a bit of a hack, we
may need to refine this later or fix clang to produce different callbacks.

Benjamin Kramer 6b23626192 [include-fixer] Add a prototype for a new include fixing tool.
Summary:
The goal of this tool is fairly simple, look up unknown identifiers in a
global database and add the corresponding #include line. It accomplishes
this by hooking into Sema as an ExternalSemaSource and responding to typo
correction callbacks. This means we can see the unknown identifier before
it's being munged by error recovery.

This doesn't work perfectly yet as some typo corrections don't emit
callbacks (delayed typos), but I think this is fixable. We also handle
only one include at a time as this is meant to be run directly from
the editing environment eventually. Adding multiple includes at the same
time is tricky because of error recovery.

This version only has a a dummy database, so all you can do is fixing
missing includes of <string>, but the indexer to build a database will
follow soon.
