=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 only chars above 255 will be
escaped using this style, other non printable chars will use octal or
common escaped patterns like C<\n>. 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, regardles of max. If the string is utf8 and
the chars value is >255 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 3 or
more digit hex value.
Returns a pointer to the escaped text as held by dsv.

=for apidoc pv_pretty
Converts a string into something presentable, handling escaping via
pv_escape() and supporting quoting and elipses.
If the PERL_PV_PRETTY_QUOTE flag is set then the result will be
double quoted with any double quotes in the string escaped. Otherwise
if the PERL_PV_PRETTY_LTGT flag is set then the result be wrapped in
angle brackets.
If the PERL_PV_PRETTY_ELIPSES flag is set and not all characters in
string were output then an elipses C<...> will be appended to the
string. Note that this happens AFTER it has been quoted.
If start_color is non-null then it will be inserted after the opening
quote (if there is one) but before the escaped text. If end_color
is non-null then it will be inserted after the escaped text but before
any quotes or elipses.
Returns a pointer to the prettified text as held by dsv.
