KongQun Yang d3903fad19 Add buffer_size UDP file options
This allows UDP receive buffer size to be increased to avoid potential
packet loss result from receive buffer overrun.

Another related flag is --io_cache_size. buffer_size in UDP options
defines the UDP buffer size of the underlying system while
io_cache_size defines the size of the internal circular buffer managed
by Shaka Packager.

Closes #411

IO Cache circular buffer full could result in UDP packet loss with UDP
inputs.

Related to #390 and #411.

fatpelt 6a8d2aa443 Add Source Specific Multicast (SSM) support
SSM can be enabled using "source" option in UDP options. Previously, "source" is considered the same as "interface", which is incorrect. 

Fixes #332.

Aaron Vaage 9e7b5c1ca9 Change CharReader to FileReader
Instead of having multiple char readers, one for strings and
one for files, just have one for files and use memory files
when testing.

KongQun Yang 8e96dd3b37 Address gcc build failures in some platforms
Seeing some failures on some platforms when compiled with clang
disabled:
  GYP_DEFINES="clang=0" gclient runhooks

Several changes to make it work:
1. Mark packager code with packager_code=1 in GYP definitions.
2. Disable a few checks in non-packager code, which we do not have
   direct control: dangling-else, deprecated-declarations,
                   unused-function
3. Fix the relevant errors in packager code.
4. Revert HAVE_STROPTS_H in curl config which is not available in
   all linux distributions.

Fixes #286
Fixes #293

KongQun Yang 82e0fd2095 Default multicast interface address to "0.0.0.0" if absent
It aligns with what a lot of other apps are doing, e.g. tsplay.

Also added notes in docker to adjust network setting if wants to use
multicast in docker container.

KongQun Yang 9c861d03f7 Report an error when disk is full
Previously packaging completes successfully without any error
or warning.

With the fix, an error will be reported if write fails. It may
appear as "Cannot close file error" as we use threaded IO, which
could delay the error reporting until Close() call, so the user
of the File API needs to make sure Close() returns successfully.

Also fixed a deadlock in threaded_io_file if internal_file->Write
fails.

Fixes #160

KongQun Yang 9e3dc06d20 Fix file permission issue with manifests
ImportantFileWriter::WriteFileAtomically uses mkstemp internally,
which set file permission to 0600, which is not what we want.
Update the code to not use mkstemp instead.

Also updated temporary file name logic to include process id in
the name so it can be unique across processes.

This avoids interference caused when two sockets are bound to the
same port in different multicast groups.
