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:
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.

we should only deduplicate symbols after matching symbols with the

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 is used to find nested classes. For a nested name foo::bar::qux we
will first look up foo::bar::qux, then foo::bar, then foo unless we find
a result. This is used to support nested classes which are not part of
the index but can only be used if the header for the parent context is
included.

This typically happens when the user didn't setup include paths correctly
and the fixer starts adding garbage includes. Avoid that. Disable the error

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.
