d03c38da7f Blacklist PGI from using conformant array parameters. (#511)
* Blacklist PGI from using conformant array parameters.

There is a bug in pgcc with conformant array parameters where the
length argument is a pointer which triggers a compiler error
(PGC-S-0094, to be specific).  The issue has been reported to PGI and
is being tracked internally as TPR 23778.  For more information, see

  https://www.pgroup.com/userforum/viewtopic.php?t=5501

* travis: Add PGI Community Edition build.

For details on the installation script, see

0749d9ca8b Fix #502 decoder bug (#505)
Decoder may have produced invalid output if:
 * at offset 0..3 dictionary word with index 3..0 for some length N is used
   and distance is encoded with direct distance code 0, and
 * at least one of next 4 commands use value from distance ringbuffer

f62cd2bcd2 brotlidump.py: disassemble brotli file (revisited) (#314)
* Create brotlidump.py

Sorry, I am a newbie. I couldn't find my file anymore when I wanted to edit it. Hope I don't waste your time.

* Fixed a bug where it couldn't read its own compression.

The problem was that a prefix code ending with a 16 "repeat" didn't realize the table was full already.
Also minor bug fixes, comments and stuff.

* Major refactoring

Rewrote almost everything.
Now can dump its own compression.

* Now more or less complete

Appears to handle all files completely (including metablock data).
Used as inspiration for the the hex example (see makehexexample.py)

9203765492 Python: Use "build" instead of "build_ext" in scripts (#460)
Previously, the Python package consisted of a single extension
module, so `build_ext` was sufficient.  Now, the package
contains a native module and an extension module, so both
`build_py` and `build_ext` are required.  Instead, run `build`,
which calls both `build_py` and `build_ext` automatically.

5632315d35 Python: Support streamed compression with the Compressor object (#448)
This adds `flush` and `finish` methods to the `Compressor`
object in the extension module, renames the `compress` method to
`process`, and updates that method to only process data.  Now,
one or more `process` calls followed by a `finish` call will be
equivalent to a module-level `compress` call.

Note: To maximize the compression efficiency (and match
underlying Brotli behavior, the `Compressor` object `process`
method does not guarantee all input is immediately written to
output. To ensure immediate output, call `flush` to manually
flush the compression buffer.  Extraneous flushing can increase
the size, but may be required when processing streaming data.
