docs: ioctl: convert to ReST

2019-07-15T12:20:26Z

Rename the iio documentation files to ReST, add an index for them and adjust in order to produce a nice html output via the Sphinx build system. The cdrom.txt and hdio.txt have their own particular syntax. In order to speedup the conversion, I used a small ancillary perl script: my $d; $d .= $_ while(<>); $d =~ s/(\nCDROM\S+)\s+(\w[^\n]*)/$1\n\t$2\n/g; $d =~ s/(\nHDIO\S+)\s+(\w[^\n]*)/$1\n\t$2\n/g; $d =~ s/(\n\s*usage:)[\s\n]*(\w[^\n]*)/$1:\n\n\t $2\n/g; $d =~ s/(\n\s*)(E\w+[\s\n]*\w[^\n]*)/$1- $2/g; $d =~ s/(\n\s*)(inputs|outputs|notes):\s*(\w[^\n]*)/$1$2:\n\t\t$3\n/g; print $d; It basically add blank lines on a few interesting places. The script is not perfect: still several things require manual work, but it saved quite some time doing some obvious stuff. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings. Signed-off-by: Mauro Carvalho Chehab
