=for apidoc pv_escape
Escapes at most the first C<count> chars of C<pv> and puts the results into
C<dsv> such that the size of the escaped string will not exceed C<max> chars
and will not contain any incomplete escape sequences. The number of bytes
escaped will be returned in the C<STRLEN *escaped> parameter if it is not null.
When the C<dsv> parameter is null no escaping actually occurs, but the number
of bytes that would be escaped were it not null will be calculated.
If flags contains C<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 C<PERL_PV_ESCAPE_NOCLEAR> is set this will not occur.
If C<PERL_PV_ESCAPE_UNI> is set then the input string is treated as UTF-8
if C<PERL_PV_ESCAPE_UNI_DETECT> is set then the input string is scanned
using C<is_utf8_string()> to determine if it is UTF-8.
If C<PERL_PV_ESCAPE_ALL> is set then all input chars will be output
using C<\x01F1> style escapes, otherwise if C<PERL_PV_ESCAPE_NONASCII> is set, only
non-ASCII chars 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 C<PERL_PV_ESCAPE_NOBACKSLASH>
then all chars below 255 will be treated as printable and
will be output as literals.
If C<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 C<PERL_PV_ESCAPE_RE> is set then the escape char used will be a C<"%"> and
not a C<"\\">. This is because regexes very often contain backslashed
sequences, whereas C<"%"> is not a particularly common character in patterns.
Returns a pointer to the escaped text as held by C<dsv>.
