1.8.1 release broke parsing of TAB-separated HINFO

[FGasper]

With 1.8.1:

> perl -MDNS::LDNS -e'DNS::LDNS::RR->new(qq<foo\t12345\tIN\tHINFO\t"hohum" "weirdo">) or die'

> perl -MDNS::LDNS -e'DNS::LDNS::RR->new(qq<foo\t12345\tIN\tHINFO\t"hohum"\t"weirdo">) or die'
Died at -e line 1.

With 1.7.1:

> perl -MDNS::LDNS -e'DNS::LDNS::RR->new(qq<foo\t12345\tIN\tHINFO\t"hohum"\t"weirdo">) or die'

DNS::LDNS being a simple Perl wrapper around the corresponding LDNS function, I’m fairly sure the breakage is from LDNS itself.

Notably, this passes in 1.8.1:

> perl -MDNS::LDNS -e'DNS::LDNS::RR->new(qq<foo\t12345\tIN\tHINFO\thohum\tweirdo>) or die'

git bisect shows that #139’s fix broke it:

    Don't skip character after having parsed a quoted token

    Fix issue #139

C demonstration of the bug:

#include "ldns/rr.h"

#define RR_STR "foo\t12345\tIN\tHINFO\t\"hohum\"\t\"weirdo\""

int main() {
    ldns_rr *rr;

    ldns_status s = ldns_rr_new_frm_str(&rr, RR_STR, 123, NULL, NULL);

    printf("LDNS parse result: %d\n", s);

    return 0;
}

The simplest fix would seem to be to revert 60773ee.
