Fix #10865
Slightly better handling of http headers from http (CONNECT) proxy. Buffers up to 128KiB of headers and raises exception if this size is exceeded.
This could be optimized further, but for the time being it does the trick.
(cherry picked from commit 8bb01d4c29e4abd5f628dbc15ab8d5cda90cdad2)
