Accept header parsing rejects valid headers

[ashokdelphia]

I'm using Chrome Version 73.0.3683.86, and the accept header it makes for regular web pages is:

Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3

With the new Accept header parsing in v3.10.0, the last entry is rejected with:

    "application/signed-exchange;v=b3" is not a valid media type

Apologies for not catching that in review for PR #216.

I think to properly follow the production in RFC 7231, we should allow other parameters and only care if q is set.

Yes. #221 should fix that.

This is fixed in v3.10.1
