Test on Linux and macOS with both gcc and clang.

Ubuntu 14.04 (trusty) is now the default travis environment.

* Use build_script step in AppVeyor configuration.  This is a
  preparation for building with multiple build systems.
* Add BUILD_SYSTEM env variable to AppVeyor build matrix.  This
  allows to switch between different build systems when building
  multiple test matrix configurations.

Update cut-and-paste description of the reset functions to reference
resetting instead of clearing.

We call ogg_stream_init() in main() of framing.c, but no
ogg_stream_clear() in corresponding. It will cause memory leak.

The git.xiph.org and github branches had diverged.

@var@ is replaced by configure when autoconf or cmake when use cmake

Just cleanup.

Output path is relative to build directory anyway according
to documentation.

Related to #9.

Fixes a cppcheck warning. Possibly we should just convert
the array type to `long` since that's what oggpack_look()
returns, using negative values to report error.

However, none of the compared values are out of range
for either type so it doesn't really matter.

Sets the correct include path when the build directory isn't the
the top source directory. Also, uses the .la file for linking,
which makes it possible to use shared libraries (and properly
build when libogg is used from a library).

Subversion, like cvs, had a mechanism for replacing inline template
text on checkout for representing things like 'last modified date'.

Git does not support this, so remove the template strings from
file header comments.

Also less aggressive language is os_types.h.

Useful for fuzzing

Bump the API documentation page footer for the latest release.

I missed this before making the 1.3.3 release, changing it
now and including this version on the website is less confusing,
I think.

These should match http://downloads.xiph.org/releases/ogg/SHA256SUMS

added missing exported functions ogg_stream_pageout_fill and ogg_stream_flush_fill to compile and use libogg under Visual Studio

On 64-bit Windows, sizeof(unsigned char *) is 8, sizeof(long) is 4 and
alignof(ogg_int64_t) is 8. This results in a 4-byte hole in ogg_packet
after "long e_o_s", which means ogg_packet structs cannot be reliably
compared by memcmp. Compare ogg_packet structs member-by-member instead.

This fixes `make check` for me on mingw-w64/GCC.

Move off the end-of-life precise base image.

Copied from the vorbis implementation by Marcel Metz.

The previous commit changed the generated source file location
without updating the installed-file list or include directories,
breaking installation and downstream integration tests.

Adding the include directory doesn't seem to be necessary on macOS,
but even the initial build step fails on Linux without it.

A false continued packet occurs if the previous page ended at the
 end of a packet, with no sequence number gap and no continued data
 on that page, while the current page has the continued packet flag
 set.
Previously, if you drained all of the buffered packet data by
 repeatedly calling ogg_stream_packetout() after submitting the
 previous page but before submitting the current page, libogg would
 discard the continued data at the beggining of the current page.
However, if you left the previous page's data in the buffer, then
 libogg would happily return the continued data at the start of the
 current page as a separate packet when you eventually did call
 ogg_stream_packetout().

This patch makes libogg consistently discard this data.

Generate config_types in the build directory instead of
the source directory.
