lib: rename Curl_strndup to Curl_memdup0 to avoid misunderstanding
Since the copy does not stop at a null byte, let's not call it anything
that makes you think it works like the common strndup() function.

Based on feedback from Jay Satiro, Stefan Eissing and Patrick Monnerat

lib: add and use Curl_strndup()
The Curl_strndup() function is similar to memdup(), but copies 'n' bytes
then adds a terminating null byte ('\0').

configure: check for the fseeko declaration too
... and make the code require both symbol and declaration.

This is because for Android, the symbol is always present in the lib at
build-time even when not actually available in run-time.

lib: use wrapper for curl_mime_data fseek callback
fseek uses long offset which does not match with curl_off_t. This leads
to undefined behavior when calling the callback and caused failure on
arm 32 bit.

Use a wrapper to solve this and use fseeko which uses off_t instead of
long.

Thanks to the nice people at Libera IRC #musl for helping finding this
out.

configure, cmake, lib: more form api deprecation
Introduce a --enable-form-api configure option to control its inclusion
in builds. The condition name defined for it is CURL_DISABLE_FORM_API.

Form api code is dependent of MIME: configure and CMake handle this
dependency automatically: CMake by making it a dependent option
explicitly, configure by inheriting the MIME value by default and
rejecting explicit incompatible values.

"form-api" is now a new hidden test feature.

Update libcurl modules to respect this option and adjust tests
accordingly.

mime: relax easy/mime structures binding
Deprecation and removal of codeset conversion support from the library
have released the strict need for an early binding of mime structures to
an easy handle (https://github.com/curl/curl/commit/2610142).

This constraint currently forces to create the handle before the mime
structure and the latter cannot be attached to another handle once
created (see https://curl.se/mail/lib-2022-08/0027.html).

This commit removes the handle pointers from the mime structures
allowing more flexibility on their use.

When an easy handle is duplicated, bound mime structures must however
still be duplicated too as their components hold send-time dynamic
information.

1a3f4c1991 mime: remove support "-" stdin pseudo-file name in curl_mime_filedata().
This feature is badly supported in Windows: as a replacement, a caller has
to use curl_mime_data_cb() with fread, fseek and possibly fclose
callbacks to process opened files.

The cli tool and documentation are updated accordingly.

The feature is however kept internally for form API compatibility, with
the known caveats it always had.

As a side effect, stdin size is not determined by the cli tool even if
possible and this results in a chunked transfer encoding. Test 173 is
updated accordingly.
