PR 21274, ld segfaults linking PE DLL
Don't use fixed size buffers for symbol names.
PR 21274
PR 18466
* emultempl/pe.em (pe_find_data_imports): Don't use fixed size
symbol buffer. Instead, xmalloc max size needed with space for
prefix. Wrap overlong lines. Formatting. Pass symbol buffer
copy of name to pe_walk_relocs_of_symbol.
(make_inport_fixup): Add "name" param, pass to pe_create_import_fixup.
* emultempl/pe.em (pep_find_data_imports): As for pe_find_data_imports.
(make_import_fixup): Add "name" param, pass to pep_create_import_fixup.
Use bfd_get_signed_* and remove unnecessary casts. Formatting.
* pe-dll.c (pe_walk_relocs_of_symbol): Add "name" param. Pass to
callback.
(make_import_fixup_mark): Add "name" param. Make use of prefix
space rather than xmalloc here.
(pe_create_import_fixup): Likewise.
* pe-dll.h (pe_walk_relocs_of_symbol): Update prototype.
(pe_create_import_fixup): Likewise.
* pep-dll.h (pep_walk_relocs_of_symbol): Likewise.
(pep_create_import_fixup): Likewise.
