48dc80bbba modutils: merge module_entry and module_info to common 
This merges the in-memory module info structures of modprobe
and depmod. This allows sharing hashing by modulename code
improving depmod runtime with almost factor of 2x.

875297378c modprobe: handle module arguments containing spaces 
Modprobe wasn't correctly parsing module arguments containing spaces from
/proc/cmdline - E.G. module.property="some text".

Extend the parsing to correctly handle quoted text.

1fd844267c modprobe-small: if concurrent module load did not succeed, wait 
usecase:
two sd cards are being mounted in parallel at same time on dual core. example
modules which are getting loaded is  nls_cp437. While one module is being
loaded , it makes state in /proc/modules as 'coming' and then starts doing its
module init function (in our case - registering nls). meanwhile on other core,
if modprobe returns that is has already been loaded, then it will continue
and search for the nls list which is not yet finished from first module init.
This fails resulting in not mounting sd card.

This fixes a regression introduced with commit 78854520 (modprobe:
revert checking for /, stop doing basename() on modprobe args,
2015-01-01) that broke modprobe options stored in /etc/modprobe.conf and
/etc/modprobe.d/*.conf.

This also fixes modprobe -r

7d16964c3e modinfo: fix module parsing with kernel >= 2.6.37 
display() function returns the length of the value we are displaying + 1.
As a consequence, if we have field=value\0field=value\0field=value in the
binary, then the second occurence will be skipped as ptr will miss the first
character of the following field.

Example trying to list aliases from ixgbe.ko on a 3.2 kernel.

- In the module we have:
alias=pci:v00008086d00001560sv*sd*bc*sc*i*\0
alias=pci:v00008086d0000154Asv*sd*bc*sc*i*\0
alias=pci:v00008086d00001557sv*sd*bc*sc*i*\0
alias=pci:v00008086d0000154Fsv*sd*bc*sc*i*\0
alias=pci:v00008086d0000154Dsv*sd*bc*sc*i*\0
...

- Using modinfo -F alias ixgbe returns:
alias:          pci:v00008086d00001560sv*sd*bc*sc*i*
alias:          pci:v00008086d00001557sv*sd*bc*sc*i*
alias:          pci:v00008086d0000154Dsv*sd*bc*sc*i*
...

This problem appeared with kernel commit "modules: no need to align .modinfo
strings" b6472776816af1ed52848c93d26e3edb3b17adab in 2.6.37.

Fix this by not trusting display() return value but increment ptr by strlen(ptr)
(the same way as depmod.c does).

07e5555a8f modprobe-small: (un)load all modules which match the alias, not only first one 
Closes 627 and 7034.

Commonly seen case is (un)loading of an alias
which matches ata_generic and a more specific ata module.

For example:

modprobe [-r] pci:v00008086d00007010sv00000000sd00000000bc01sc01i80
(ata_generic and pata_acpi)

modprobe [-r] pci:v00001106d00000571sv00001509sd00009022bc01sc01i8a
(ata_generic and pata_via)
