This will allow per-session adjustments and also significantly lower the risk of inconsistent calculations in the rate limit code during parameter changes. Ref #3996

Noticed while porting #3998 to the 6.0 branch with a varnishtest more sensitive to timing.

With #3998 we need to ensure streams are not going to skip vcl_recv if reset faster than reaching this step for the request task. The alternative to prevent the vcl_req_reset feature from interfering is to simply disable it.

The error check is not performed in a critical section to avoid contention, at the risk of not seeing the error until the next transport poll.

Once a client is reportedly gone, processing its VCL task(s) is just a waste of resources. The execution of client-facing VCL is intercepted and an artificial return(fail) is returned in that scenario. Thanks to the introduction of the universal return(fail) proper error handling and resource tear down is already in place, which makes this change safe modulus unknown bugs. This adds a circuit breaker anywhere in the client state machine where there is VCL execution. A new Reset time stamp is logged to convey when a task does not complete because the client is gone. This is a good complement to the walk away feature and its original circuit breaker for the waiting list, but this has not been integrated yet. While the request is technically failed, it won't increase the vcl_fail counter, and a new req_reset counter is incremented. This new behavior is guarded by a new vcl_req_reset feature flag, enabled by default. Refs #3835 Refs 61a15cbf Refs e5efc2c8 Refs ba54dc91 Refs 6f50a00f Refs b8816994

The goal is for top-level transports to report whether the client is still present or not.

It was particularly hard to follow once we reach client c3.

This adds parameters h2_rst_allowance and h2_rst_allowance_period, which govern the rate of which we allow clients to reset h/2 streams. If the limit is exceeded the connection is closed. Mitigates: #3996

this is required for autoconf 2.71, but I have kept the required version at 2.69 and tested that the changes are compatible. Most of the changes come from autoupdate, with this change: AC_PROG_CC_STDC is obsolete, but older autoconf versions do not set the highest possible c standard. So we keep AC_PROG_CC_C99 because we actually require c99, while AC_PROG_CC_STDC could fall back to c89 For varnish.m4, we should apply the same canonical settings as for varnishd itself

... except for ax_with_curses.m4 which requires PKG_CHECK_EXISTS which, apparently, cci does not have should we consider again to not have them and rather require autoconf-archive be installed?

Otherwise we end up with a broken output outside of MacOS: checking whether daemon() works... checking for daemon... yes Now it's one or the other: checking whether daemon() works... no checking for daemon... yes If we want to lie, we should at least be good at it.

By conditionally setting vmod_*_vcc variables in includes we can get rid of a double definition warning.

Adds coverage for tab characters at start/end of field value. Regarding the "fo o" " bar" header, it cumulates an error in the name and another in the value, but only one of them will trigger the expected PROTOCOL_ERROR. Only the invalid "fo o" is checked now, and the other error is part of the new coverage. Signed-off-by:

Control characters will be caught by vct_ishdrval() anyways, but this condition would also reject allowed obs-text non-ASCII characters. Signed-off-by:
