[PATCH v2 0/6] meson: miscellaneous system detection fixes

Principally motivated to handle an issue where these were failing to detect the system properly, on Solaris.

Eli Schwartz (6):
  meson: simplify and parameterize various standard function checks
  meson: check for getpagesize before using it
  meson: do a full usage-based compile check for sysinfo
  meson: add a couple missing networking dependencies
  meson: fix typo in function check that prevented checking for
    hstrerror
  meson: only check for missing networking syms on non-Windows; add
    compat impls
