Project-agnostic helpers for use with autosetup

[sgbeal]

It was recently my pleasure to port the sqlite project from autotools to autosetup¹. Part of that process involved creating utility code for autosetup and, because i use autosetup in a number of trees, i split much of that utility code into a project-agnostic collection which can be re-used across my various projects (some of it was derived from such projects but is not actually used in the sqlite tree).

The current state of that is:

https://sqlite.org/src/file/autosetup/proj.tcl

It's my hope that something in there will be of use to other autosetup users, with the following caveats:

• That particular copy of that particular file is the "canonical" version of that file, and is intended to be copy/pastable into arbitrary autosetup-using trees, but it also makes no API stability guarantees. That is: any of the functions defined there may undergo interface changes at any time, as it suits the sqlite project.

• TCL is not my "native language," so parts of this code may well not follow idioms which experienced TCL coders would have chosen.

Trivia: approximately 1/3rd of the sqlite project's configure code is in that file. The rest is fairly project-specific and is in its own module.
