Import analysis_services.dart into analysis_server.dart.

Import analysis_services.dart into analysis_server.dart.

Having two separate packages doesn't really have any benefit, and has
the downside of forcing us to carefully avoid circular dependencies
between the two.  It makes more sense to just combine them.

This is largely a mechanical change consisting of the following renames:

1. pkg/analysis_services/lib/src/* -> pkg/analysis_server/lib/src/services/*
2. pkg/analysis_services/lib/* -> pkg/analysis_server/lib/src/services/*
3. pkg/analysis_services/test/* -> pkg/analysis_server/test/services/*

There were 4 instances where 1 and 2 created a collision:
.../services/correction/assist.dart, .../services/correction/fix.dart,
.../services/refactoring/refactoring.dart, and
.../services/search/search_engine_internal.dart.  To fix the
collision, the files coming from pkg/analysis_services/lib/src were
renamed to "..._internal.dart".

In addition, pkg/analysis_services/test/test_all.dart was modified to
call pkg/analysis_services/test/services/test_all.dart.
