Per discussion on https://codereview.chromium.org/1839803002/ it also makes sense to remove net_small, cronet_small and few other targets, which were used to produced smaller binaries as part of regular Android build, and use gyp/gn variables to configure Cronet builders.

The following revision refers to this bug:

  https://chromium.googlesource.com/chromium/src.git/+/abe280e7da8b757d8f622cc9c9421880aaa38231

commit abe280e7da8b757d8f622cc9c9421880aaa38231
Author: kapishnikov <kapishnikov@chromium.org>
Date: Thu Apr 14 19:07:16 2016

Remove net & url small, iOS ICU alternatives, unit tests.

1. Removed |net_small| and |url_small| targets.
2. To keep supporting the small builds, introduced |use_platform_icu_alternatives|
   boolean flag that indicates whether the net and url targets should be
   built with ICU alternatives. The default value of the flag is false.
3. Removed |cronet_static_small| target.
4. Renamed 'define' USE_ICU_ALTERNATIVES_ON_ANDROID to
   USE_PLATFORM_ICU_ALTERNATIVES.
5. Added use_platform_icu_alternatives=1/true to gyp/gn cr_cronet.py.
6. Changed cronet_reduction_proxy component to stop using net & url small.
7. Removed |common_small| template from data_reduction_proxy/core/common
8. Removed |google_apis_small| template from google_apis.
9. Added simplistic ICU alternatives for iOS
10. Fixed linking problem when net_unitests were build with GN (not all
    websockets tests were excluded when enable_websockets was set to false).
11. Added support for net_unitests for the small net/url variation
    (there were no tests for it before).
12. Created the list of unit tests that are failing with the current
    alternative ICU implementations on Android and iOS. Added them to the
    exclude list.
13. Added new flag 'disable_brotli_filter' which is false by default.
    Set the flag to true in cr_cronet.py.
14. Converted 'define' USE_PLATFORM_ICU_ALTERNATIVES to build flags.

The current number of passing tests:
net_with_icu_alternative iOS: 12548
net_with_icu iOS: 14549
net_with_icu_alternative Android: 15000
net_with_icu Android: 15223
url_with_icu_alternative iOS: 49
url_with_icu iOS: 91
url_with_icu_alternative Android: 50
url_with_icu Android: 92
