e4383b8f1e Add SkFILEStream constructor which takes a size.
Allows the user to limit the stream to a subset of the entire file.
SkFILEStream uses the current FILE position as the base position for the
stream; this allows the user to further limit the length of the stream
to a range of bytes in the file.

bb60c2149e Refactor SkFILEStream for clarity.
Rename fSize to fEnd (since it is actually the offset of the end
underlying file, not the size of the file), fOriginalOffset to
fStart, and fOffset to fCurrent. Also initialize in the order fEnd,
fStart, then fCurrent to maintain the invariant that fCurrent should
always be kept within the range of fStart and fEnd, inclusive.

7571f9e490 Replace 'typedef xxxxx INHERITED' with 'using INHERITED = xxxx;'.
Mechanically updated via Xcode "Replace Regular Expression":

  typedef (.*) INHERITED;
    -->
  using INHERITED = $1;

The ClangTidy approach generated an even larger CL which would have
required a significant amount of hand-tweaking to be usable.

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.

No-Presubmit: true

6943689ab4 clean up includes
Prepare SkRegion.h, SkShader.h, SkStream.h for documentation.
Name params, add trailing commas to enum member list,
move or remove some public SkRegion.h stuff.

SkRegion gets a minor overhaul to move some pieces
to private: or SkRegionPriv. The intent is to preserve the
current code so that the fixes for documentation do not impact
performance or code size.

8a8a144952 Treat SkFILEStream's fOriginalOffset as the start
Bug: b/78866720

::rewind() rewinds to fOriginalOffset
::seek(position) seeks to position + fOriginalOffset
::move(offset) will not move < fOriginalOffset
::getPosition() returns position relative to fOriginalOffset
::getLength() returns full size minus fOriginalOffset
::duplicate() and ::fork() pass on fOriginalOffset

Android may create an SkFILEStream using a file descriptor whose offset
is at the beginning of the data that Android cares about. Treat all
positions in SkFILEStream as relative to that original offset.

This allows AnimatedImageDrawable to read directly from the
SkFILEStream, rather than using an SkFrontBufferedStream and forcing
SkGifCodec to cache data for later use.

This fixes a TODO that was introduced in
https://skia-review.googlesource.com/c/skia/+/9498 and takes it a step
further. In that CL, bungeman@ and I discussed the change and decided to
"leave this alone for now to avoid changing behavior". Doing a code
search today, the only two callers want the new behavior.

a93a14a998 Convert NULL and 0 to nullptr.
This was created by looking at warnings produced by clang's
-Wzero-as-null-pointer-constant. This updates most issues in
Skia code. However, there are places where GL and Vulkan want
pointer values which are explicitly 0, external headers which
use NULL directly, and possibly more uses in un-compiled
sources (for other platforms).

f93d71122e SkFontData to use smart pointers.
The SkFontData type is not exposed externally, so any method which uses
it can be updated to use smart pointers without affecting external
users. Updating this first will make updating the public API much
easier.

This also updates SkStreamAsset* SkStream::NewFromFile(const char*) to
std::unique_ptr<SkStreamAsset> SkStream::MakeFromFile(const char*). It
appears that no one outside Skia is currently using SkStream::NewfromFile
so this is a good time to update it as well.

cbc060a700 SkWStream::writeText inlined.
Motivation: This function is used throughout SkPDF.

Note that the compiler can usually inline the result of strlen() for literal strings.

Before:
    out/Release/nanobench -m WStreamWriteText -q
        Timer overhead: 24.2ns
        ! -> high variance, ? -> moderate variance
            micros   	bench
              6.10  	WStreamWriteText	nonrendering

After:
    out/Release/nanobench -m WStreamWriteText -q
        Timer overhead: 23.9ns
        ! -> high variance, ? -> moderate variance
            micros   	bench
              2.51  	WStreamWriteText	nonrendering

PDF runtime change: -0.8% ±0.04%.

d61c384342 Allow SkStream::peek() to partially succeed
If the stream can peek less than requested, peek that amount. Return
the number of bytes peeked.

This simplifies crrev.com/1472123002. For a stream that is smaller than
14 bytes, it can successfully peek, meaning the client will not need to
fall back to read() + rewind(), which may fail if the stream can peek
but not rewind.

This CL revives code from patch set 3 of crrev.com/1044953002, where I
initially introduced peek() (including tests).

Add a test for SkFrontBufferedStream that verifies that peeking does
not make rewind() fail (i.e. by reading past the internal buffer).

2766c00fc0 remove SkInstCnt
It's been outclassed by Valgrind and leak sanitizer,
and it seems to be causing problems for external folks building Skia.

I'm not sure why our own builds seem unaffected.

028a4135aa Add a method to read a stream without advancing it.
Add a virtual method on SkStream which will do a "peek" some bytes, so
that those bytes are read, but the next call to read will be
unaffected.

Implement peek for SkMemoryStream, where the implementation is simple
and obvious.

Implement peek on SkFrontBufferedStream.

Add tests.

Motivated by decoding streams which cannot be rewound.

5cffba8d8e Remove SkMemoryStream::peek()
I'd like to add a new API to SkStream for peeking - i.e. reading some
bytes without advancing the stream. This will be implemented for the
streams where it makes sense. I think the function should look
something like the following:

size_t peek(void* buffer, size_t bytesToRead) {
     return this->onPeek(buffer, bytesToRead);
}

virtual size_t onPeek(void* buffer, size_t bytesToRead) {
    return 0;   // unimplemented base class.
}

In order to avoid confusion, I'd like to remove SkMemoryStream::peek(),
which is not currently used internally, by Chrome, or by Android as far
as I can tell. There is also another function does the same thing:
getPosition().
