Description:
A small library for parsing and canonicalizing URLs

Local Modifications:
1. src/base directory:
- Remove the include of base/base_export.h. Define BASE_EXPORT as empty string.
- Wrap namespace base with namespace url to distinguish from google3 base.
- src/base/strings/string16.*
  * PrintTo function and operator << are removed to eliminate dependency on
    src/base/strings/utf_string_conversion.
- src/base/strings/string_piece.*
  * Add constructor for ::string.
  * Change DCHECK_IS_ON() to !NDEBUG.
- src/base/strings/string_util.*
  * Removed the include of base/compiler_specific.h.
  * Only the needed functions are kept.
- src/base/third_party/icu/icu_utf.cc
  * Add base/macros.h and FALLTHROUGH_INTENDED for fall-through switch cases.

2. src/url directory:
- Use google3 version of //base, //util/gtl/lazy_static_ptr.h,
  //third_party/icu and //testing/base/public:gunit_main. Some users don't want
  googleurl to be dependent on google3 (e.g. geo/render/mirth/net:googleurl),
  so we try our best to do it.
- Change NOTREACHED() to DCHECK(false).
- src/url/origin.cc
  * Remove the include of base/strings/string_number_conversions.h.
- src/url/scheme_host_port.cc
  * Remove the includes of base/numerics/safe_conversions.h and
    base/strings/string_number_conversions.h.
  * Include url/url_canon_internal.h.
  * Replace base::checked_cast with static_cast.
  * Change base::UintToString to _itoa_s, which is used in other places.
- src/url/url_canon_icu.cc
  * Replace LazyInstance with google3 LazyStaticPtr, modify intialization
    and access methods accordingly.
- src/url/url_util.cc
  * Replace ANNOTATE_LEAKING_OBJECT_PTR() with google3
    HeapLeakChecker::IgnoreObject(), and only use it when GOOGLEURL_IN_GOOGLE3
    is defined.
- src/url/url_canon_icu.h and src/url/url_canon_stdstring.h
  * Remove the include of src/base/compiler_specific.h.
- src/url/third_party/mozilla/url_parse.cc
  * Compile filesystemurl related function only when NO_FILESYSTEMURL_SUPPORT
    is not defined, so that wireless/android/icing/lib/core doesn't need to
    depend on other googleurl srcs as well as third_party/icu.

3. google3_additions directory:
2014-07-30: added google3_additions/googleurl_init.cc, which properly
initializes googleurl during InitGoogle().
