- tests-tsprintf.patch: Avoid testsuite failure with glibc >= 2.37

- Update to mpfr 4.2.0
* New functions mpfr_cosu, mpfr_sinu, mpfr_tanu, mpfr_acosu, mpfr_asinu,
mpfr_atanu and mpfr_atan2u.
* New functions mpfr_cospi, mpfr_sinpi, mpfr_tanpi, mpfr_acospi, mpfr_asinpi,
mpfr_atanpi and mpfr_atan2pi.
* New functions mpfr_log2p1, mpfr_log10p1, mpfr_exp2m1, mpfr_exp10m1 and
mpfr_compound_si.
* New functions mpfr_fmod_ui, mpfr_powr, mpfr_pown, mpfr_pow_uj, mpfr_pow_sj
and mpfr_rootn_si (mpfr_pown is actually a macro defined as an alias for
mpfr_pow_sj).
* Bug fixes.
In particular, for the formatted output functions (mpfr_printf, etc.),
the case where the precision consists only of a period has been fixed
to be like ".0" as specified in the ISO C standard, and the manual has
been corrected and clarified.
The macros of the custom interface have also been fixed: they now behave
like functions (except a minor limitation for mpfr_custom_init_set).
- Remove mpfr-4.1.1-patch01.patch which is included in the new release.
