The internal memory allocator had an extra code to keep a list of blocks
for small size allocation. This would help to reduce the interactions
with the system malloc as the memory would be already allocated from the
system, but there's an extra cost associated with that - all the
allocations/deallocations must be locked, effectively eliminating any
optimizations in the system allocator targeted at multi-threaded
applications. While the isc_mem API is still using locks pretty heavily,
this is a first step into reducing the memory allocation/deallocation
contention.
feature-test tool location needs to be determined by its associated
variable; otherwise, the tool is not found on Windows:

Run this check only when in Git repository, because the run.sh function
which produces the "file not removed" warning is run only when build
directory is the same as the source directory, that is only for in-tree
builds.
In DNS Flag Day 2020, the development branch started setting the
IP_DONTFRAG option on the UDP sockets. It turned out, that this
code was incomplete leading to dropping the outgoing UDP packets.
Henceforth this commit rolls back this setting until we have a
proper fix that would send back empty response with TC flag set.
updated the parser to allow the "port", "tls" and "http"
paramters to "listen-on" and "listen-on-v6" to be specified in any
order. previously the parser would throw an error if any other order
was used than port, tls, http.
unencrypted DoH connections may be used in some operational
environments where encryption is handled by a reverse proxy,
but it's going to be relatively rare, so we shouldn't make it
easy to do by mistake. this commit changes the syntax for
listen-on and listen-on-v6 so that if "http" is specified, "tls"
must also be specified; for unencrypted listeners, "tls none"
can be used.
As libssl depends on libcrypto, -lssl needs to precede -lcrypto in
linker invocations or else the build will fail with static OpenSSL
libraries. Adjust m4/ax_check_openssl.m4 to prevent this issue from
getting triggered when pkg-config files for OpenSSL are not available.
Commit fa505bfb0e omitted two unit tests
while introducing the SKIP_TEST_EXIT_CODE preprocessor macro. Fix the
outliers to make use of SKIP_TEST_EXIT_CODE consistent across all unit
tests. Also make sure lib/dns/tests/dnstap_test returns an exit code
that indicates a skipped test when dnstap is not enabled.
The only reason for including the gssapi.h from the dst/gssapi.h header
was to get the typedefs of gss_cred_id_t and gss_ctx_id_t. Instead of
using those types directly this commit introduces dns_gss_cred_id_t and
dns_gss_ctx_id_t types that are being used in the public API and
privately retyped to their counterparts when we actually call the gss
api.
This also conceals the gssapi headers, so users of the libdns library
doesn't have to add GSSAPI_CFLAGS to the Makefile when including libdns
dst API.
The lmdb.h doesn't have to be included from the dns/view.h header as it
is separately included where used. This stops exposing the inclusion of
lmdb.h from the libdns headers.
The <isc/readline.h> header provided a compatibility shim to use when
other non-GNU readline libraries are in use. The two places where
readline library is being used is nslookup and nsupdate, so the header
file has been moved to bin/dig directory and it's directly included from
bin/nsupdate.
This also conceals any readline headers exposed from the libisc headers.
The extra library CFLAGS were causing the headers to be included in
wrong order possibly pulling header files from previously installed
BIND 9 version.
This commit cleans up the extra <foo>_CFLAGS from the includes in favor
of not exposing 3rd party headers in our own header files.
