itchyny e001deb4cf Strip UTF-8 BOM at the start of each input file (#3657)
The UTF-8 BOM was stripped only at the start of the parser stream, but jq
feeds all input files into a single parser, so a BOM at the start of the
second and later files reached the parser as content and failed with a
confusing "Invalid numeric literal" error. Strip it in the file readers
instead, at the start of each input file including stdin, and in
jv_load_file.

This also strips the BOM for raw input, so -R and --rawfile no longer
yield a leading U+FEFF, and a BOM at the start of a -f program file or an
imported module is now accepted rather than reported as a syntax error.
In exchange, "\uFEFF1" | fromjson is now a parse error, since a U+FEFF
inside a string is content rather than an encoding marker, and the
dedicated "Malformed BOM" error is gone.
