the wishbone package

In wishbone_pkg.vhd, the new g_sdb_name generic was added to
xwb_crossbar instead of xwb_sdb_crossbar. Fixed

- sdb_rom: add parameter g_sdb_name
- xwb_sdb_crossbar: add parameter g_sdb_name
- wishbone_pkg: f_string_fix_len add parameter justify_right
- wishbone_pkg: f_sdb_auto_device add parameter name
- wishbone_pkg: f_sdb_auto_bridge add parameter name

wishbone/wb_gpio_port: match length of gpio_b to gpio_in when g_num_pins is not an exact multiple of 32. Closes #1532

They finally don't help much and they break simulation as Modelsim complains
about types conversion.

Fix it the same way as f_x_to_zero() is fixed in wbgen.

It fixes some functions not well understood by Vivado synthesis

it was de-asserted at wrong value (too early/late). This was making
to misbehave the modules that depend on this signals.

New function expects textfile with binary representation of each word in a
separate line, e.g.:
10011000000000000000000000000000
11010000000000000000000000000000
11010000001000000000000000000000
01111000000000010000000000000000
00111000001000010000000000000000

This for example reduces WRPC SPEC reference design synthesis time from ~26
minutes to ~11 minutes.
