Installing LuaJIT sometimes fails with SHA256 mismatch

[mpeterv]

Reproduced locally for LuaJIT 2.1.0, again, get the expected file with prefix and suffix, prefix is e8119\r\n and suffix is the same, \r\n0\r\n\r\n. Reproduction done using urllib.urlretrieve, which is what hererocks calls.

[mpeterv]

Calling urlretrieve in a loop shows that the first download for each url is broken, the following ones are OK. Perhaps either github or urlretrieve handle chunked encoding incorrectly?..

[mpeterv]

Using curl --verbose, indeed, GitHub appears to use Transfer-Encoding: chunked, but only on the first request for each url, with a reset after some delay.

[mpeterv]

Of course, the "prefix" is file length in hexadecimal, so the broken file is just full chunk encoded file. Not sure why GitHub decides to send the whole file in one chunk, or why urlretrieve can't handle it,

[mpeterv]

OK, so urllib doesn't support chunked transfer (httplib has functions for working with it but they are not used), but urllib2 does, and so does urllib.request from Python 3.

Fixed in @a9b8ab9.
