string_view_metadata was introduced to make compiled format relocatable.
However, format string compilation is an optimization and therefore
adding overhead and extra complexity for relocation is undesirable.
In most cases the string will be either static or outlive compilation
and formatting and if it doesn't, it's possible to make compiled
representation relocatale by other means.
gcc-9 gives the following shadow warning:
```
In file included from /Users/libraries/ioss/src/fmt/ostream.h:12,
from /Users/libraries/ioss/src/Ioss_DatabaseIO.C:59:
/Users/libraries/ioss/src/fmt/format.h: In function 'void fmt::v6::internal::parse_format_string(fmt::v6::basic_string_view<Char>, Handler&&)':
/Users/libraries/ioss/src/fmt/format.h:2442:10: warning: declaration of 'struct fmt::v6::internal::parse_format_string(fmt::v6::basic_string_view<Char>, Handler&&)::writer' shadows a global declaration [-Wshadow]
2442 | struct writer {
| ^~~~~~
/Users/libraries/ioss/src/fmt/format.h:1703:7: note: shadowed declaration is here
1703 | using writer = basic_writer<buffer_range<char>>;
| ^~~~~~
```
Since the `writer` struct is only used internally in the `parse_format_string` function, its name can be changed somewhat aribtrarily to avoid conflicts with names in an outer scope.
Note that this warning is also present in the 6.0.0 release.
Refactor `format_specs` and related APIs to support variable-width fill
(#1109), improve naming consistency, remove legacy setters (#940), and
optimize layout.
see https://github.com/google/oss-fuzz/pull/2381
the history of the fuzz branch is long and messy and
is difficult to rebase on top of the current master.

stop high memory use when fuzzing
count_code_points(basic_string_view<char8_t>) was defined in
fmt/format-inl.h, and only declared in fmt/format.h, but not defined
in src/format.cc. This commit moves the overload to fmt/format.h and
inlines it.
