Description

I plan to add more wrappers for Posix structures. Many of them use types not supported in PyMemberDef, like uint32_t or pid_t. So the first step is to add support of many standard C and Posix integer types.

gh-114388 and gh-115011 were preparations to this step.

The open question: should we assign new codes for new types or define them as aliases to existing types if they are already exist (for example, Py_T_PID can be an alias of Py_T_INT, Py_T_LONG or Py_T_LONGLONG, depending on platform).

Research direction

Start by reviewing the preparations in gh-114388 and gh-115011, then inspect the work in gh-117032 and gh-132550. Resolve whether new PyMemberDef type codes or platform-dependent aliases are appropriate, and define support for the standard C and POSIX integer types described in the issue.
