lib/libc/stdlib: getenv.3 getenv.c putenv.c setenv.c
Log message:
modernise getenv/setenv/putenv/unsetenv:
• drop historic setenv("foo=","=bar") setting "foo" to "bar"
as prodded by dalias
• getenv("foo=bar") now doesn’t getenv("foo")…
• many more EINVAL checks for sanity
• all are now environ==NULL safe
• size_t not int
• document instances touched explicitly (cf. commitid 100568BF70414C190EB
but cid 100568C1B486A69D09B also, which reverted getenv to first match,
as something in Perl broke…)
