Fábio Coutada 7855eab092 feat(import): Complete PikeOS 5.0 ecosystem import from devvm-arch 
MAJOR MILESTONE: Successfully imported complete PikeOS 5.0 ecosystem
from Virtual Machine 100 (devvm-arch) on gigabyte Proxmox server.

Import Summary:
- Source Code: 4.3GB, 63,441 files, 14,829 C/C++/H files
- Documentation: 78MB, 37+ PDF manuals covering all PikeOS aspects
- XSD Schemas: 1.8MB, 158 schema files for configuration/code generation
- Test Framework: Complete TFW infrastructure in src/tfw/

Key Components:
✅ Multi-architecture kernels (ARM v7/v8, PowerPC e500/e500mc/e5500, x86_64)
✅ Core source libraries (libstand, ssw, p4ext)
✅ Complete test framework with executables, includes, libraries
✅ 37+ comprehensive PDF documentation (installation, development, platform manuals)
✅ 158 XSD schemas for Eclipse-based code generation and configuration
✅ AUTOSAR/MISRA safety-critical compliance foundation
✅ Hardware virtualization support
✅ Eclipse IDE project configuration (.project, .cproject)

Documentation Categories:
- Installation & User Guides (pikeos-installation-guide.pdf, user manuals)
- Development References (kernel, driver, test framework manuals)
- API & Programming (C/C++ environments, native API extensions)
- Platform Manuals (ARM, PowerPC, x86 specific guides)
- CDK Documentation (gcc, binutils, ld, cpp internals)
- Release Notes (all components for 5.0.3)
- Specialized Topics (hardware virtualization, POSIX compliance)

Technical Achievements:
✅ Complete PikeOS 5.0 codebase across multiple processor architectures
✅ Safety-critical foundation with AUTOSAR/MISRA compliance
✅ Eclipse IDE integration with XSD-driven code generation pipeline
✅ Comprehensive test framework for validation and verification
✅ Complete documentation covering development, deployment, and optimization

Extraction Method:
- Source: VM 100 (devvm-arch) on gigabyte server (192.168.0.104)
- Method: Direct LVM disk mount via losetup, rsync transfer
- Size: Total 4.4GB extracted and organized

Next Phases:
- Phase 3: XSD Workflow Analysis (Day 8-10)
- Phase 4: Safety Standards Compliance Documentation (Day 11-12)
- Phase 5: Component Categorization (Day 13-14)
- Phase 6: Aurelio Brain Test (Day 15)

<p>Mount a remote network file system (NFS). </p>
<p><br />
Attempts to mount file system <em>remotefs</em> from the host specified by <em>addr</em> to the local directory <em>mountpoint</em>. The interpretation of <em>addr</em> is specific to the RPC transport implementation. <br />
For the ANIS RPC transport layer, <em>addr</em> is interpreted as an object of type <em>sockaddr_in</em>, with structure members <em>sin_family</em> set to PF_INET, <em>sin_addr</em> set to the NFS server address. The <em>sin_port</em> field is ignored. <br />
For the lwIP RPC transport layer the address length parameter <em>addr_len</em> determines whether the address <em>addr</em> is interpreted as an object of type <em>sockaddr_in</em> or <em>sockaddr_in6</em>, with address family set to either PF_INET or PF_INET6 in structure members <em>sin_family</em> and <em>sin6_family</em> respectively, NFS server address in <em>sin_addr</em> and <em>sin6_addr</em> and <em>sin_len</em> to the length of the address. The <em>sin_port</em> and <em>sin6_port</em> fields are ignored. <br />
If not the null pointer, <em>args</em> points to additional parameters applied to subsequent operations on the mounted file system. If <em>args</em> is the null pointer, the following defaults apply:</p><ul>
<li>Protocol version 0, i.e. mount is attempted with all supported protocol versions.</li>
<li>UID 0 (nobody).</li>
<li>GID 0 (nogroup).</li>
<li>No supplemental GIDs.</li>
<li>Transfer size 2048 bytes for read, write, and read directory entries.</li>
<li>Attribute cache enabled, name cache enabled, read-write mount, privileged port number of NFS protocol RPC, (flags=NFS_MNT_USE_PRIV).</li>
<li>Attribute cache timeout 5 for regular files and 30 for directories.</li>
<li>1000000 number of retransmissions.</li>
<li>16 name cache hash chains, 128 name cache entries.</li>
</ul>
<p>For NFS version 2 transfer sizes are silently limited to 8192 (protocol restriction) and may be further limited by the optimum transfer size advertised by the NFS server. If transfer sizes are set to zero, the server advertised optimum transfer size is used instead. The maximum size for the supplemental GID list is 16 entries. The RPC transport connection timeout is one second, retransmissions are issued after a timeout of 1, 2, 3, and 4 seconds, and then continue every 5 seconds. The first timeout diagnostics message is issued after 15 seconds, then every 5 seconds. <br />
The name cache is only supported when using NFS version 3. One name cache entry consumes about 520 bytes, memory for all name cache entries is allocated at mount time. The validity of name cache entries is determined by the attribute cache timeout values for the respective type of the entry (file or directory). When use of READDIRPLUS is enabled, reading directory entries populates the name cache.</p>

<p>Contains a combination (bitwise OR) of diagnostics flags such as NFS_DIAG_ERR, NFS_DIAG_WARN, or NFS_DIAG_TRACE and function identifiers such as NFS_DIAG_MOUNT, NFS_DIAG_NFSPROC, etc. <br />
Diagnostics flags enable certain types of messages and module identifiers select which modules of the implementation have diagnostics messages enabled. <br />
Diagnostics messages include the thread identifier (pthread_self()) of the calling thread, name of the function, and diagnostics control flags and module identifier used to produce the message. <br />
The output message is formatted as follows: <br />
<code>NFS 0xTTT func() FM Text...</code> <br />

<li>TTT Thread identifier</li>
<li>func Function name</li>
<li>F Diagnostics control flag</li>
<li>M Module identifier</li>
<li>Text.. Message text.</li>

<p>Diagnostics control flags are encoded as follows:</p><ul>
<li>NFS_DIAG_WARN W</li>
<li>NFS_DIAG_ERR E</li>
<li>NFS_DIAG_RPC_TIMEO R</li>
<li>NFS_DIAG_TRACE t</li>
