c0bd9f9fe5 rewrite includes to not need so much -Ifoo
Current strategy: everything from the top

Things to look at first are the manual changes:

   - added tools/rewrite_includes.py
   - removed -Idirectives from BUILD.gn
   - various compile.sh simplifications
   - tweak tools/embed_resources.py
   - update gn/find_headers.py to write paths from the top
   - update gn/gn_to_bp.py SkUserConfig.h layout
     so that #include "include/config/SkUserConfig.h" always
     gets the header we want.

5776508126 Add a SkRWBuffer reserve mechanism
Currently, Chromium stores segmented data in a SharedBuffer and appends
to SkRWBuffer one segment at a time:

        const char* segment = 0;
        for (size_t length = data->getSomeData(segment, m_rwBuffer->size());
            length; length = data->getSomeData(segment, m_rwBuffer->size())) {
            m_rwBuffer->append(segment, length, remaining);
        }

This can yield a bunch of just-above-4k allocations => wasted RAM due to
internal fragmentation.

Ideally, we'd want a SkRWBuffer::reserve(size_t bytes) API, but the
current internals don't support that trivially.

Alternatively, the caller can pass a reserve hint at append() time.

6351640285 Fixes for SkRWBuffer
Do not call SkBufferHead::validate in SkROBuffer's destructor, which
may be called in a separate thread from SkRWBuffer::append. validate()
reads SkBufferBlock::fUsed, and append() writes to it, resulting in
a data race.

Update some comments to be more clear about how it is safe to use
these classes across threads.

Test the readers in separate threads.

In addition, make sure it is safe to create a reader even when no
data has been appended. Add tests for this case.

Mark a parameter to SkBufferHead::validate() as const, reflecting
its use.
