Subject: memdebug: stop tracking send and recv
X-Git-Tag: rc-8_18_0-3~2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a585cc35e57fc06806443207e31a244c9df029bb;p=thirdparty%2Fcurl.git

memdebug: stop tracking send and recv

- they rarely catch any problems
- we have other ways to test different send/recv problems
- the number of such calls vary much more per invoke than others, making
  memdebugging harder
- reducing the total number of fallible functions per test is good
- they were not used as intended anyway

Closes #20097
