This patch restricts the section names matched in coff_section_type,
a function that translates section names to symbol type, and arranges
to translate section flags to symbol type before looking at names.
The latter change resulted in various test failures due to improper
section flags being used in tests, and by the plugin support, so fix
that too.
The new test fails on many ELF targets that lack .init/fini_array
in their scripts. I've just xfailed those. pru-elf oddly defines
__init_array_begin rather than __init_array_start. I've left that
target as a FAIL, and pj-elf too which reports an error for undefined
weak symbols.

* syms.c (coff_section_type): Only allow '.', '$' and numeric
following the standard section names.
(bfd_decode_symclass): Prioritize section flag tests in
decode_section_type before name tests in coff_section_type.
* plugin.c (bfd_plugin_canonicalize_symtab): Init fake_section
and fake_common_section using BFD_FAKE_SECTION. Use "fake" as
their names and choose standard .text section flags for
fake_section.

This gets rid of the couple of linker failures for visium-elf:
FAIL: ld-elf/pr14156b
FAIL: ld-elf/pr22677
by tweaking the respective testcases. The first tweak is the same as the
one made to the sibling testcase ld-elf/pr14156a.d about one year ago and
the second tweak adds the usual main/start/_start/__start symbols.

* testsuite/ld-elf/pr14156b.d: Adjust for extra symbols.
* testsuite/ld-elf/pr22677.s: Define main/start/_start/__start.
