Clear up log1p, ldexp, scalbn, scalbln compat handling.
This patch cleans up how compat symbols / long double versioning are handled for log1p, ldexp, scalbn and scalbln functions. The general principle is to do as much as possible through the type-generic templates. Previously, when errno-setting wrappers were added the compat long double symbols were left pointing directly to the underlying implementations; they are moved to point to the errno-setting wrappers. For the functions also present in libc, compat symbol handling for the libc copies needs to go in ldbl-opt wrappers, but the type-generic templates can handle it for the libm copies. There is no need for w_scalbln_template.c to disable the creation of an unused internal alias (such code made sense in the context of patches trying to avoid any changes to generated code for ease of comparison, but can be removed in a change that specifically does intend to change details of where symbols point). Tested for x86_64, and with build-many-glibcs.py. * math/w_scalbln_template.c (strong_alias): Do not undefine and redefine. * sysdeps/ieee754/ldbl-opt/s_ldexp.c (declare_mgen_alias): Remove macro. (ldexpl): Only define as compat symbol for libc, not libm. (scalbnl): Define as compat symbol for libc here. * sysdeps/ieee754/ldbl-opt/s_ldexpl.c (declare_mgen_alias): Only define for [IS_IN (libc)]. (__ldexpl_2): Remove alias. (ldexpl): Only define with long_double_symbol if [IS_IN (libc)]. (scalbnl): Likewise. Use __wrap_scalbnl not __ldexpl_2 as base name in long_double_symbol call. * sysdeps/ieee754/ldbl-opt/s_log1p.c: Remove file. * sysdeps/ieee754/ldbl-opt/s_scalbln.c: Likewise. * sysdeps/ieee754/ldbl-opt/s_scalbn.c: Likewise. * sysdeps/ieee754/ldbl-opt/w_log1p.c: Likewise. * sysdeps/ieee754/ldbl-opt/w_scalbln.c (declare_mgen_alias): Remove macro. [IS_IN (libc) && LONG_DOUBLE_COMPAT (libc, GLIBC_2_1)] (scalblnl): Define as compat symbol.
