QUIC: clear SSL_OP_ENABLE_MIDDLEBOX_COMPAT on SSL context switch.
The SSL_OP_ENABLE_MIDDLEBOX_COMPAT option is provided by QuicTLS and enabled
by default in the newly created SSL contexts. SSL_set_quic_method() is used
to clear it, which is required for SSL handshake to work on QUIC connections.
Switching context in the ngx_http_ssl_servername() SNI callback overrides SSL
options from the new SSL context. This results in the option set again.
Fix is to explicitly clear it when switching to another SSL context.

15 * To change the process title in Linux and Solaris we have to set argv[1] | |
16 * to NULL and to copy the title to the same place where the argv[0] points to. | |
17 * However, argv[0] may be too small to hold a new title. Fortunately, Linux | |
18 * and Solaris store argv[] and environ[] one after another. So we should | |
19 * ensure that is the continuous memory and then we allocate the new memory | |
20 * for environ[] and copy it. After this we could use the memory starting | |
21 * from argv[0] for our process title. | |
22 * | |
23 * The Solaris's standard /bin/ps does not show the changed process title. | |

24 * You have to use "/usr/ucb/ps -w" instead. Besides, the UCB ps does not |
452 | 25 * show a new title if its length less than the origin command line length. |
26 * To avoid it we append to a new title the origin command line in the | |
27 * parenthesis. | |
