Subject: fixes #10456,#12928 issues when chaining templates to sortedByIt
 (#15734)

* update c_malloc's to csize_t

fix for broken --os:ios

* I'm an idiot sorry

* Create talgorithm.nim

* workaround for #10456

I don't understand the intricacies of how lambdalifting and template expansions interact with lent, so i don't know how to fix the real problem, but this sidesteps whatever issue that is.

* working test, use typeof rather than auto
