=for apidoc pv_escape
Escapes at most the first "count" chars of pv and puts the results into
dsv such that the size of the escaped string will not exceed "max" chars
and will not contain any incomplete escape sequences.
If flags contains PERL_PV_ESCAPE_QUOTE then any double quotes in the string
will also be escaped.
Normally the SV will be cleared before the escaped string is prepared,
but when PERL_PV_ESCAPE_NOCLEAR is set this will not occur.
If PERL_PV_ESCAPE_UNI is set then the input string is treated as Unicode,
if PERL_PV_ESCAPE_UNI_DETECT is set then the input string is scanned
using C<is_utf8_string()> to determine if it is Unicode.
If PERL_PV_ESCAPE_ALL is set then all input chars will be output
using C<\x01F1> style escapes, otherwise if PERL_PV_ESCAPE_NONASCII is set, only
chars above 127 will be escaped using this style; otherwise, only chars above
255 will be so escaped; other non printable chars will use octal or
common escaped patterns like C<\n>. Otherwise, if PERL_PV_ESCAPE_NOBACKSLASH
then all chars below 255 will be treated as printable and
will be output as literals.
If PERL_PV_ESCAPE_FIRSTCHAR is set then only the first char of the
string will be escaped, regardless of max. If the output is to be in hex,
then it will be returned as a plain hex
sequence. Thus the output will either be a single char,
an octal escape sequence, a special escape like C<\n> or a hex value.
If PERL_PV_ESCAPE_RE is set then the escape char used will be a '%' and
not a '\\'. This is because regexes very often contain backslashed
sequences, whereas '%' is not a particularly common character in patterns.
Returns a pointer to the escaped text as held by dsv.
